Changes for v2:
* Ioremap every dts node used in the patches.
* Check the board compatible string to see if the board supports deep sleep.
* Can not reserve the first page of DDR memory, because PPC64 doesn't support
changing the kernel base address. So still save and restore the first 128 bytes
of DDR memory.
* Still save and restoer CCSR registers in kernel, because bootloader doesn't
know what register values to restore
* Changed copyright and email address from freescale to NXP
