mtd: nand: add mrvl-nand driver ...

The driver is taken from the Linux kernel, with the following changes :
 - all DMA removed
 - all asynchronous handling removed, including the interrupt handler,
   and the asynchronous state handling
 - pxa armada support removed

Most the kernel structure was kept, to ease up future fixes integration
from the kernel driver.

The driver is tested on a pxa3xx system development
board (aka. zylonite), and reading, writing, erasing, and bad block
management were tested.

The macb/gem core is used by the Zynq SoC.  In preparation of sharing
the macb driver between at91 and Zynq, rename the platform data to

location.
