The LCD driver is unified and lcd_send_command now takes 2 arguments : the command and its argument.
If there is no argument, it's set to 0 and a NOP command is issued
If there is more than one argument (set X/Y address), the 2nd argument is sent as a 2nd command, and a NOP command is issued after it.
Benefit : c200v2 transfers the command and the argument in one 16 bits transfer
Performance should not be affected since commands without argument are only used in lcd_init() and lcd_enable()
lcd_send_data() now transfers whole lines (or columns) instead of single pixels
yuv is disabled for c200v2 for now
Some buttons can be read, including left button (bit 6 of DBOP_DIN), but for some reason they have no effect in rockbox: to be investigated
