Data types and I/O functions have been defined for
64 bit physical addresses in arm.

Signed-off-by: Aneesh Bansal <aneesh.bansal@freescale.com>

Changes in v2:
There is no need for defining 64 bit I/O operations.
If an IP needs to do 64 bit access, it will do it by defining
32 bit addr_hi and addr_lo.
