This caused LCD problems on the ErosQ, where the screen would
go white until being put through a sleep/wake cycle. The exact
reason for this isn't obvious, but the problem didn't exist
prior to the AXP driver rewrite.
The two dependent changes,
42999913ba - x1000: Increase USB current limit to 500 mA at all times
90dd2f84a9 - x1000: Correctly limit USB charging current
ended up bringing the USB charging situation back to where it
was prior to the rewrite, so the cleanest option is to revert
the whole lot.
This reverts commit 42999913ba.
This reverts commit 90dd2f84a9.
This reverts commit 2d89143962.

This problem actually had nothing to do with USB boot; it's
because the cable is plugged in when the USB mode menu item
is selected. The USB thread detected the select button press
and went into charge-only mode (as it usually does when you
hold down a key in Rockbox). This is fixed by having the USB
thread ignore most keys in the bootloader.
USB connect events are delivered via the button queue, and
there were also cases where the connection could be missed
if the event happened within another UI screen. This should
also be fixed.

I noticed a few mistakes in the old driver code and it was in
need of an overhaul anyway... I decided to scale things back,
simplify the code and remove most of the debug menus, netting
a nice code size savings.
One new feature is an advanced debug menu which is accessible
by recompiling the code with AXP_EXTRA_DEBUG. It adds quite a
bit of code size and isn't useful other than for development
so it must be manually enabled by editing the source.

This allows battery run time to be calculated from the
actual battery usage on the FiiO M3K and Shanling Q1.
This isn't very good for the time being and the estimate
tends to go all over the place due to small variations
in current or voltage.
The Eros Q can support this feature as well, but since
it already has fixed estimates defined and the quality
of the "real time" estimate is low I am not enabling it
there.

The FT6x06 driver used for the Shanling Q1's touchscreen

Multi-touch is only useful in 3x3 grid mode since the Rockbox

Upon getting a USB reset, the USB core will update charging
current by calling usb_charging_maxcurrent_change(). On all
current X1000 targets this may cause a hang, since changing
the charge current involves a blocking I2C transaction.
Eg. if the host issues a reset when we're already configured
as part of error recovery, the change from 500 mA -> 100 mA
will cause a hang.

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.

A reasonable default assumption for a user
would be that they can plug their device into
a USB AC adapter and it will charge with as much
current as it reasonably can. With the previous
default, an AC adapter will only do 100mA, basically
a trickle charge.
Make this configurable default per-device, so as not
to break old devices without testing.
Define TARGET_USB_CHARGING_DEFAULT to USB_CHARGING_FORCE
to use the new default.

- SD Card
- Battery level and charging/not charging status
- USB
- audio
- sample rate switching
- HP / LO detect, with "safe" fixed LO volume -

- LCD shows abnormal effects under some circumstances: for example,

After conducting some simplistic tests, I found that the power usage
did not appear to be affected by the CPU frequency.
I tested by playing back a 44.1 KHz FLAC file on single track repeat,
and measured current with the AXP173's battery discharge current ADC.
The button and LCD backlights were set to always on. Headphones were
unplugged and the volume was muted to eliminate any influence from
the headphone amp.
On average the current usage was between 78-81 mA at 1008 MHz, 252 MHz,
and 112 MHz. If anything, 1008 MHz drew _less_ current than the lower
frequencies, by about 1-3 mA.
A possible explanation for this, assuming it's not just a bias of the
test, is that the CPU idle state saves so much power that it's better
to maximize the real time that the CPU spends idling. More systematic
testing is needed to confirm this.

Tested on eros q, everything measured from line out,
open circuit.
- volume steps were approximately double the dB they
were labelled as, so "-2 dB" would result in a change
of about -4 dB from maximum (0, +6.2dBV)
- maximum volume defining the line out volume only
changed every 10 values, and then was not close
to correct- "-10 dB" resulted in -2.5 dB from maximum
This gets the volume dB approximately correct, and
maximum volume correctly sets the line out volume.
I was unable to get odd values in the max volume
to work, so set the step size to 2 instead of one.
For "consumer level" (-10dBV), set to -16.
For "Pro level" (+4dBu -> ~1.8dBV), set to -4.
