Based on a patch by Amaury Pouly which was based on a patch from Ryan
Hitchman.
I mainly moved the code for polling into the tuner driver so it can be
reused by other targets. I added the CONFIG parameter for the polling
frequency (in ticks) to save energy. Also, I did some minor cleanups.

IMHO the current name is somewhat misleading:
- usb_drv_send() is blocking and we have usb_drv_send_nonblocking()
for the non-blocking case. This inconsistent naming can only
promote confusion. (And what would we call a blocking receive?)
- Other hardware abstraction APIs in Rockbox are usually blocking:
storage, LCD, backlight, audio... in other words, blocking is the
default expected behavior, with non-blocking calls being a rarity.

It has only a couple GB of onboard flash storage with no storage
driver in Rockbox. It hasn't seen any meaningful development since
its initial commit, it's not on the build farm, and the bootloader
build is broken by other refactoring.

Do not introduce any change for M:Robe 500 as it uses the two LCD frames
in non-obvious way.
Sansa Connect and Creative ZVM use only single front framebuffer.
Place TTB at DRAM end to minimize memory loss due to alignment.
Reserve as little as possible memory for the LCD frames.
On Sansa Connect this change extends audio buffer by 858 KiB.

AVR interrupt signal can remain active if the state has changed during
state read. In such case, there won't be intterupt and the interface
would appear unresponsive until AVR thread received event (e.g. USB
connection/disconnect). Solve the issue by not waiting for event if AVR
interrupt signal is active prior to event wait.

Make it possible for target to provide voltage, percentage and time to
empty values. The voltage measurement is nice to have in debug menu even
if the actions are taken only based on percentage. Perform battery level
estimation based on voltage only if percentage is not available.
Use time to empty based on actual power consumption. This makes the
estimated runtime displayed in Rockbox Info to react to backlight
setting. The bq27000 updates time to empty estimate every 5.12 seconds
so it is possible to see the estimate with backlight off on the screen
if user enters Rockbox Info, activates hold switch, waits 11 seconds and
releases the hold switch.

Import non-free firmware image from linux-firmware package.
Firmware loading works but is disabled at compile time because just

AVR requires bigger delays between retries. Read state instead of
version for synchronization purposes as it shifts more bytes.

If the commands repeatedly fail it is likely that the AVR is not
programmed. In such case simply continue normal operation. This is
especially important in bootloader as it makes it possible to load new
rockbox build using bootloader USB mode. Otherwise, the only recovery
option would be to use I2C serial.

Use 32-bit monotime AVR counter for time tracking. Set the time by
adding fixed offset to the counter value. Store the offset in rockbox
directory to make it persistent between reboots.
Do not implement alarm functionality as wakeup is only possible from
sleep and not from complete power off.

This uses an equivalent algorithm but with a different initial value
than we normally use (all bits off vs all bits on). Use the new crc_32r
to replace the original MI4 crc32 implementation.
This frees up some extra space on mi4 targets which gives us more
room on a few very space constrained targets (sansa c200/e200, etc).

Wait on semaphore until DMA finishes instead of busy waiting. This
allows the CPU to be used by other tasks during transfers.
Increase peripheral clock frequency, divide AHB by 2 instead of 3.
Function clock frequency is AHB divided by MMC divider + 1.

Disabling double buffering results in expected CPPI TX behaviour. With
the double buffering enabled, sending single ZLP resulted in two ZLPs
being available. The two ZLPs is problematic because this causes Windows
to reset USB device after failed SCSI command.
The problematic sequence on Windows 10 was as follows:
* Host sends SCSI Mode Sense(6) Informational Exceptions Control(0x1C)
* Device sends ZLP
* Device sends command failed response
With endpoint double buffering enabled the ZLP was read twice by host.
As host was expecting command response on the second read (and got ZLP
instead), host attempts recovery by resetting USB device and retrying.

Acknowledge SYS_USB_CONNECTED in all queues so USB task can gain

Reduce CPPI requeue timeout to speed up disk access.

Correctly set endpoint maximum packet size so host will not consider
end of transfer after receiving first packet when transfer is larger
than 64 bytes (at High Speed the endpoint max packet size was set to
64 but according to descriptor it is 512).
Split DMA transfers up to CPPI_MAX_FRAG so we get single interrupt
after each call to tnetv_cppi_send().

Clearing recoverzap parameter exists the Recovery Mode. This makes it
possible to run Rockbox on Sansa Connect without relying on original
Linux firmware.
Enable write-through cache on flash memory as write-back complicates
handling without any real benefits. The flash memory accepts commands
as series of writes at predefined addresses, so it is important that
the cache does not interfere with the writes.
