According to RM0433 the DCTRL register needs to be written
after DLENR and DTIMER. This is respected for data transfer
commands but not for non-data commands. Nothing bad seems
to be happening because of this, but it seems wise to rectify
the issue.

According to RM0433 consecutive writes to the CLKCR and CMDR
registers must be separated by at least 7 AHB clock cycles.
The initialization code didn't respect this and it seemed to
be causing a nasty bug, where the SDMMC bus clock got stuck
at 400 KHz in hardware. Despite the CLKCR register reading
back the correct value, it could not be written with a new
value even in the debugger; resetting the peripheral was the
only way out of this state.
Adding some dummy register reads after any access to CLKCR
should insert the necessary number of wait states. Without
the fix, the SDMMC clock gets stuck about 12% of the time.
With this fix, the clock always initializes correctly.

If not, these devices will charge very slowly (0.07A) when plugged into a wall plug, and will all discharge slowly when docked & playing music.
Enabling this option (that is already enabled by default on some other devices like erosq and fiio m3k) make them pull between 0.20 and 0.30. They charge faster, just as fast as on Stock OS, and won't discharge when playing music while docked.

Replace the factor calculation from pcm-alsa.c, which
is based on signal *power* ratios, with the fp_factor()
calculation that is based on amplitude ratios. Because
power changes with the square of amplitude, this means
1 dB of power equals 2 dB of amplitude.
Rockbox's volume controls are amplitude-based, so the
smallest step size for pcm-alsa was effectively 2 dB.
The fp_factor() method supports 0.1 dB steps and is a
bit more accurate besides, so it's simply superior in
all respects (aside from taking a few more CPU cycles
to calculate the factor).

Disabling an IRQ in the NVIC may not take effect right away;
if the IRQ is being disabled to implement a critical section
it's necessary to follow up with dsb + isb to serialize the
NVIC update. Add a helper function for doing this.

pcm_play_stop -> audio_stop at startup / mixer_channel_stop at shutdown
pcm_is_playing -> mixer_channel_status
All of these have been removed from the plugin API. Updated API docs to
clarify role of audio_stop() vs mixer_channel_stop()
Todo: get rid of pcm_play_[un]lock().

lrcplayer currently automatically scrolls the lyrics for you, as it assumes that there is sync information in the lyrics. In the case where there aren't (like for ID3V2 USLT tags), the plugin will automatically assume timestamps and will scroll automatically.
This commit adds an option in the Display Menu to allow automatic scrolling to be disabled. When disabled, you can scroll the lyrics using the volume keys (like you would on the iPod's OS).

The problem with drive strength and things not working reliably
at 50 MHz turned out to be entirely caused by the ESD diodes on
the data/command/clock lines, which have a whopping 200-300 pF
junction capacitance -- 6-10x higher than the 30 pF limit given
by the MMC spec.
After desoldering the diodes the bus seems stable at 50 MHz and
with any drive strength (note MEDIUM is still fast enough even
for 50 MHz, so the drive strength is unchanged).

I have a 1TB SD card that gets filesystem corruption when writing large
amounts of data when using Rockbox in USB storage mode. The card doesn't show
this behaviour when using the original firmware or when using an external SD
card writer.
This is on an Aigo Eros Q device. Same brand 512GB card does not exhibit this
behaviour.
Whether this specific SD card explicitly requires CMD23 or if there's a
problem with the controller's timing of auto-CMD12 in combination with this
card is currently unknown, but implementing it does solve the problem.
This change request implements CMD23 by first probing if SBC is supported by
the SD card and then using it instead of AUTO_CMD12.

The driver didn't handle the busy signal at the end of
some command responses (R1b response type), notably the
CMD12 (STOP_TRANSMISSION) sent after a multiblock write
would time out because DTIMER==0 and leave the DPSM in
an incorrect state for the next command, causing a hang.

When doing I/O, the interrupt can rarely fire with no
active command and no status bits set. This is probably
because the interrupt is set pending by the NVIC while
the handler is already running, so should be harmless.
