With the introducing of generic board and ARM-based cores, current
deep sleep framework doesn't work anymore.
This patch will convert the current framework to adapt this change.
Basically it does:
1. Converts all the Freescale's DDR driver to support deep sleep.
2. Added basic framework support for ARM-based and PPC-based
cores separately.

Reading DDR register should use ddr_in32() for proper endianess.
This patch fixes incorrect waiting time for ARM platforms.

Initially it was believed the DDR controller on Freescale ARM would have
big endian. But some platform will have little endian.
