[PATCH] ARM: mm: use phys_addr_t for physical address when populating pud

[will.deacon@arm.com (Will Deacon)]

When creating our initial mappings, we call alloc_init_pud, which
simply defers to alloc_init_section for mappings at the pmd level.

However, the physical address passed to alloc_init_pud is potentially
truncated to unsigned long, which could cause problems on systems making
use of LPAE.

This patch fixes the function prototype to use phys_addr_t.
