99f9550881 H300, X5: Optimised lcd_yuv_blit(), using line-pair zig-zag writing to the LCD controller. ~7% speedup on H300, ~5% speedup on X5.

60b01fa0f7 Straignten out some issues with HAVE_LCD_ENABLE. 1g/2g/3g had it defined but it shouldn't have been. lcd_enabled() was only available as a real function on gigabeat but others can use that too. Markup lcd.h a bit because I got a bit lost in it.

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.

bcd94a9b01 Accepted FS #5786 by Michael Sevakis - lcd_yuv_blit() for X5. 
hard coded to YUV4:2:0 for now, gives ~13.5 fps.

1. X5 lcd sleep
2. #define HAVE_LCD_ENABLE
3. add "backlight (on hold switch)" setting, adapted from FS #5735

Note that the while(1) yield ==> asm("halt") part is NOT commited here,
I prefer it would be discussed separately.
