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

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%

H300: (1) Use DMA for LCD updates, with auto-aligned line reads. Speeds up LCD updates by ~ 75% at 11MHz and 45MHz. Only ~ 11% speedup at 124MHz due to (2). (2) Less aggressive LCD transfer timing at 124MHz. With the previous timing, slightly corrupted display contents was reported, and with DMA transfers at least 4 waitstates are needed to make updates work at all. * A table in system-iriver.c shows settings for all integer multiples of the base clock frequency (info for developers, not yet complete).

H300: * Assembler optimised lcd_yuv_blit(), based on the X5 version. 23..31% speedup in tests depending on video size. * Don't set HORIZ_RAM_ADDR_POS for LCD updates, it's unnecessary. * Started the target tree move for H300 with this.
