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.
