1a56fcea9f fsl/deepsleep: avoid the DDR restore from being optimized out 
Function dp_ddr_restore is to restore the first 128-byte space
of DDR. However those codes may be optimized out by compiler
since the destination address is at 0x0. In order to avoid
compiler optimization, we restore the space from high address,
which is not at 0x0, to low address.

a7787b7850 fsl/sleep: updated the deep sleep framework for QorIQ platforms 
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.
