Daniel Mack c316f577b4 mtd: OMAP: Enable GPMC prefetch mode
Enable GPMC's prefetch feature for NAND access. This speeds up NAND read
access a lot by pre-fetching contents in the background and reading them
through the FIFO address.

The current implementation has two limitations:

 a) it only works in 8-bit mode
 b) it only supports read access

Both is easily fixable by someone who has hardware to implement it.

Note that U-Boot code uses non word-aligned buffers to read data into, and
request read lengths that are not multiples of 4, so both partial buffers
(head and tail) have to be addressed.

Tested on AM335x hardware.
