ARM: 6671/1: LPAE: use phys_addr_t instead of unsigned long in outercache functions

The unsigned long datatype is not sufficient for mapping physical addresses
>= 4GB.

This patch ensures that the phys_addr_t datatype is used to represent
physical addresses when passed to the outer cache functions. Note that the
definitions in struct outer_cache_fns remain as unsigned long because there
are currently no outer cache implementations supporting physical addresses
wider than 32-bits.
