Saves 100+ bytes (50 of it in iram), saves a bit of power
Internal LCD clock decreased but with added efficiency of drawing routines
loses only around 2 Hz on the scanrate (~75Hz) while fps is slightly increased
Column offsets are now calculated outside the loops saving a few instructions
Passing a LCD_NOP command after lcd_update turns off Data/Cmd# gpio
saving a bit more power
Added a function lcd_write_cmd_triple() that allows 3 commands to be sent at once
when enabled with LCD_USE_FIFO_FOR_COMMANDS it sends them back to back without
checking FIFO status in between or sending to thhe D/C# Gpio.
Makes an assumption about the FIFO being large enough to
accept 3 commands after being emptied which should be the case on the
clipv1, clipv2, clipplus. I have only enabled it for the clip plus
as thats the only device I have to test it on.
On clip+ the SSP clock is now turned off when screen is off

move prototypes to ascodec.h
move code to ascodec*.c
YPR0: use adc-as3514.c instead of duplicating it
TODO: merge as3514.h and ascodec.h ?

Merge clipv1/clipv2 code since they use the same 3x3 matrix
clipzip keyscan buttons now work in bootloader
clipplus untouched (no matrix)

fuzev2 button_read_device() runs in interrupt context so writes are atomic

The new controller framebuffer (different from what is in clipv1/clipv2 and some clip+) has 128 columns, the old has 132 columns and is centered on the screen.

Charge using 150mA current like the OF to charge faster
Edit clipv2 charging curve with 150mA

We can write to DBOP_DOUT in 8 bits mode : bits 7..0 are mapped to the
LCD, not bits 15..12 and 3..0 like on Clipv1

Select it based on as3535/as3525v2 so Clip+/Fuzev2 will be able to use
it too

Reuse some code from Clip (LCD) and a lot of code from AS3525
Add a new CPU type : AS3525v2, identical to AS3525 except it's an ARMv5 (arm926-ejs)
SD code still not working
For an unknown reason LCD doesn't work anymore (to be investigated)
