Prevent startup screen flash by properly using AVR LCM functions. Power
off LCD when not needed to improve battery runtime.

Add defines for all commands handled by AVR, including the unknown
opcodes (0xC5, 0xD3, 0xD4, 0xD5, 0xD6).
Properly synchronize with AVR and keep repeating command until it looks
like AVR has accepted it.

Change all lcd drivers to using a pointer to the static framebuffer
instead of directly accessing the static array. This will let us
later do fun things like dynamic framebuffer sizes (RaaA) or
ability to use different buffers for different layers (dynamic
skin backdrops!)

This improves framerate update (when uboosted, approximate values) from 151 fps to 911 fps for whole screen update and from 432 fps to 3017 fps for quarter screen update.

Massage the way it interfaces a bit to make things more flexible.
The chroma_buf scheme on Sansa Connect and Creative ZVx calling the
lcd_write_yuv420_lines implementation in lcd-as-memframe.S with five params
with a chroma buffer that the function can't use wouldn't work anyway so just
have them use the stock implementation (really, how was that working?).

This should prevent buffer underruns that can occur during heavy use of buttons or scrollwheel.

Included are drivers for buttons, backlight, lcd, audio and storage.
