HiFi E.T. MA8 is almost the same as MA9 except
another DAC(pcm1792 in ma8, df1704 in ma9).
MA8 has ILI9342 lcd, MA8C has ILI9342C lcd.

The only difference between this target and HiFi E.T. MA9
is display driver (ILI9342 in MA9 and ILI9342c in MA9C)

button_read_device() could be called before pca9555_read_thread
intializes pca9555_in_ports variable, and return incorrect value.

When using variadic macros there's no need for IF_MD2/IF_MV2 to deal
with function parameters. IF_MD/IF_MV are enough.
Throw in IF_MD_DRV/ID_MV_VOL that return the parameter if MD/MV, or 0
if not.

The idea is to share loading code between bootloaders and rolo().

This speeds up partial updates quite a bit but what is more
important it opens up a way to efficiently implement
lcd_blit_yuv() using hw colorspace conversion.
Tested on rk27generic, hm60x v1 and v2 and on ma9.
Benchmark for hm60x v1 (by mortalis):
HEAD patched
1/1 141fps 138fps

commit_discard_dcache_range() is used in sd, lcd and pcm drivers
to handle transfers form/to data buffers so this should not introduce
any problems. It is reported to fix pop noise observed on some hifimans.
We apparently don't fully understand cache handling on this platform.

If interrupts trigger during cache invalidation this could cause memory
corruption. This should be right fix for commit_discard_idcache in
contrast to 72ebcbf and c1ec1ec.

It seems something wrong with cache handling in rk27xx. OF always disable cache
before invalidating cache ways, therefore, now we do the same.
Hopefully this will fix cache handling, but I couldn't contend that it's really so.

Several HM-801 DAPs have another buttons circuit.
This patch adds support for such devices so they could work properly.

We should cast to (volatile uint32_t*) here, because attempt to refer to volatile
object through use of an lvalue with non-volatile-qualified type will result in
undefined behavior.

This version resembles how OF handle cache invalidates.
This seems to fix mysterious data aborts on plugin/codec loading
after introducing frequency scaling.
Credit goes to mortalis for pinpointing the reason of aborts.
