Convert both instances of the apple stop sign constant
to char array instances. This ensures sizeof will work
as expected when applied to the constant.

Although data transfer is reliable with DMA, it seems to cause hangs
and lockups during the early stages of connection and it's not clear
what the cause might be.

This only required a minor patch to the usb-designware driver due
to DMA requiring physical addresses -- on the X1000, these differ
from virtual addresses so we have to do the usual conversion.
Both the mass storage and HID drivers work, but there are a few
issues so this can't be considered 100% stable yet.
- Mass storage might not be detected properly on insertion,
and USB has to be replugged before it shows up
- HID driver may occasionally panic or hang the machine

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.

There's no point including this in normal builds: the stats are not
used for anything, they are not really of interest to anyone except
developers, and add a small overhead to the kernel tick.

Initializing the clocks in the SPL brings Rockbox in line with
how the FiiO M3K's original SPL works. It's likely other X1000
devices do this too.
There was a logic error in the previous setup: the code falsely
assumed that DDR memory would always be running from MPLL, but
it would be switched to APLL by the bootloader. Rockbox would
then try to re-init APLL, albeit with the same parameters. Maybe
this was the cause of the boot hang on some units.

What we really want is to avoid any interrupts being generated
before the drivers which handle them are properly initialized.
Intead of trashing all GPIOs, search for the problem pins and
fix them, leaving the others alone.
This fixes the M3K's button light flickering on boot and should
stop the M3K from entering a potentially confusing "dead" state
where all the lights are off but the CPU is still on.

SPL is now designed so core X1000 code is in control of the boot,
under the reasonable assumption that the device boots from flash.
It should not be too hard to adapt to other X1000 ports.
The biggest functional change is that the SPL can now read/write
the flash, under the control of a host computer. The SPL relies
on the boot ROM for USB communication, so the host has to execute
the SPL multiple times following a protocol.

It turns out that aa_cache.buf, used to store decoded album art during
background scanning, was not correctly allocated and overlapped with
memory allocated for buflib. This was what caused all the segfaults.
Also fixed a logic error in read_pfraw(), which returns a buflib handle
on success, but also returned 0 on failure -- since 0 is a valid buflib
handle, it should return -1 on failure instead.

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.

This is basically the same problem as FS#13272, except it happens
on certain themes, eg. rayboradio. The issue only affects targets
with decimal volume levels.
Tested the fix using the rayboradio theme on the FiiO M3K and the
Fuze+ simulator. Volume was displayed correctly on both.

With a full-scale 440Hz tone, the line out voltage
measured approx. 5.8Vpp at the 0 setting. WAY too hot!
(9 dBV, in fact)
For 0.894Vpp (-10 dBV - consumer devices), -18 appears to be
about right for line level signals, but for "pro" equipment
a different level may be desired.
Therefore, the user to cap the line out level by re-using the global
volume limit setting.

Inline assembly in RoLO and the FiiO M3K bootloader used 'jr' to
jump to a newly loaded Rockbox binary, but incorrectly left the
branch delay slot open. That gives GCC an opening to place illegal
instrutions, etc, which might cause an unhandled exception.
