ARM asm LCD and ATA driver functions: Don't save r12 as it is a scratch reg. Saves a bit of stack and execution time.

Sansa Clip : save one instruction per 8 pixels loop in lcd_grey_data
...
We set directly the needed bits to write into DBOP_DOUT (15:13 and 3:0)
Since we can't set the mask 0xf00f with one mov instruction, revert the
logic and use orrne instead of biceq (in the whole function for consistency)
