Zhao Qiang - Nov. 7, 2013, 2:29 a.m.
P1010rdb-pa and p1010rdb-pb have different mtd of nand.
So update dts to adapt to both p1010rdb-pa and p1010rdb-pb.

Move the nand-mtd from p1010rdb.dtsi to p1010rdb-pa*.dts.
Remove nand-mtd for p1010rdb-pb, whick will use mtdparts
from u-boot instead of nand-mtd in device tree.
