ARM: uniphier: fix warnings reported by aarch64 compiler

The UniPhier SoC family has not supported ARMv8 yet, but these would
cause warnings if they were compiled with a 64bit compiler.  Before
adding the ARMv8 support really, fix them now.

Because UniPhier SoCs do not support Large Physical Address Extension,
casting "phys_addr_t" into "unsigned long" would carry the address
as is.
