mpc85xx/t104x: Add deep sleep framework support
When T104x soc wakes up from deep sleep, control is passed to the
primary core that starts executing uboot. After re-initialized some
IP blocks, like DDRC, kernel will take responsibility to continue
to restore environment it leaves before.

Driver/ddr: Add support of different DDR base address
DDR base address has been the same from the view of core and DDR
controllers. This has changed for Freescale ARM-based SoCs. Controllers
setup DDR memory in a contiguous space and cores view it at separated
locations.

Driver/DDR: Update DDR driver to allow non-zero base address
The DRAM base has been zero for Power SoCs. It could be non-zero
for ARM SoCs. Use a macro instead of hard-coding to zero.

powerpc/mpc8xxx: Extend DDR registers' fields
Some DDR registers' fields have expanded to accommodate larger values.
These changes are backward compatible. Some fields are removed for newer
DDR controllers. Writing to those fields are safely ignored.
TIMING_CFG_2 register is fixed. Additive latency is added to RD_TO_PRE
automatically. It was a misunderstanding in commit c360ceac.
