[U-Boot] [PATCH 2/3][v2] Data types defined for 64 bit physical address

[Aneesh Bansal]

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

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.
