[MTD] [NAND] Fix endianess bug in ndfc.c

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

The writel() call accidentally clears all bits in the NDFC_CCR
register (endianess problem). Now __raw_writel() is used instead.

Tested on Bamboo with NAND on chip select 0 and chip select 1.
