f8b1da2f7b H300, X5: Faster lcd_yuv_blit() using EMAC. Speedup of the function itself at 124MHz: 10.5% on X5, 16.5% on H300. mpegplayer speedup 3..4%

10363b3a81 Get rid of some OR-ing and conditional expressions in lcd driver when register values can just be saved in shorts. Touch-up to comment in asm part.

1102afb0b0 Disables hard dither mode on the x5 for routine drawing. Display driver automatically enables it when needed. Full screen frame rate up to 48 at normal CPU frequency from about 45 putting it about where it was when everything including the framebuffer was in IRAM due to the shorter and simpler lcd_write_data. Please advise if this works differently on any x5 as this might be considered a hack since nothing in the datasheet specifies using the chip this way. It is perfectly functional on mine.
