This does not scale the EMI frequency and keep the processor
betweel 261MHz and 454MHz. It can still be improve. The auto-slow
divisor could still be change, 8 seems reasonable for now

Implemented scheme:
ARM AHB APB
Normal 50 50 50 MHz
Max 200 100 50 MHz
Frequency scaling is disabled on rk27generic due to too
slow lcd updates when running with 50MHz AHB.
battery_bench shows ~1h runtime improvement on hifiman.

Remove the old debug stuff about VDDx and add a clean api to
get/set the regulator (VDDD, VDDA, VDDIO, VDDMEM). This is useful
for proper frequency scaling.

Due to the way Archos devices (i.e. the only HWCODEC devices) boot,
memory is tight these days. Disabling LOGFDISK on them will make them
work for now. In the long term a better solution is needed.

Implement cache aligned transfer of more than one sectors. The
current code now transfers almost all data at once by moving
it within the buffer to make it cache aligned. This greatly
improves the performance of the transfers, especially in mass
storage mode.

Further merge drivers by using the same command and data functions.
No use one mutex per drive instead of a global sd lock. Fix the
RCA handling which was different between SD and MMC (shifted 16)
and thus confusing. Add MMC commands definition to the mmc.h
header similarly to the SD one. Change MMC handling a bit by
selecting/deselecting on each transfer like SD, which allows
for several MMC devices in theory and is more uniform.

Merge sd and mmc drivers into a single sdmmc driver. This allows
some factoring of the code and simplify bug fixing. Also fix the
dma/cache related issue by doing all transfers via a correctly
aligned buffer. The current code is not smart enough to take
advantage of large user buffers currently but at least it is safe!

There are tricky DMA/cache related issue on the imx233 which could
pop up with the old driver. The new one ensures that all dma
tranfers are cache safe by using an intermediate buffer.

Reduce DMA maximum transfer size since transfering 64Kb requires
to set a size of 0 and it's not worth adding checks everywhere
to handle this special case. Also add statistics about unaligned
transfer (wrt to cache). Update debug screen accordingly and
simplify it so it can fit smaller screens too.

Keeping the touchscreen pressed during a screen transition can lead
to accidental actions. action_wait_for_release() currently doesn't work
properly for touchscreen, so it's better to not transition before release.

with no button pressed.
If e.g. two yesno screens directly follow each other the button release of the
first one was incorrectly accepted in the second one. The fix exposed another
problem in action.c if action_wait_for_release() is called when no button is
actually pressed. The next press was silently eaten.
This time re-introducing FS#12723 is avoided by leaving the offending hunk
out in yesno.c.
