In core_mmu_add_mapping() requested physical address
rounded up/down to granule size (0x100000), which leads
to establishing of virtual mappings with overlapped
physical counterparts. If two virtual mappings overlaps
due to such roundings, then following phys_to_virt() can
implicitly return result of virtual address from
unexpected mapping. This patch fix such behavior by
returning virtual address of newly established mapping.
