83aded979f 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).

9af13c327e 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.
