Subject[PATCH 02/10] (un)xlate_dev_mem_ptr: use phys_addr_t for the @phys parameter
To read/write 64-bit physical addresses on 32-bit architectures,
the type must be changed to phys_addr_t. It is also semantically
more exact.

Note that the default xlate_dev_mem_ptr() is defined as a macro,
so no adjustment is needed there.
