PATCH 1/1 powerpc/83xx: add NAND support for the MPC8360E-RDK boards

The StMicro NAND chip (512Mbit, 64MB) is connected to the local bus, the first local bus' user-programmable machine is configured by the firmware to work with NAND chips.

QE GPIO pin is used to poll the NAND's Ready-Not-Busy signal.
