[ Upstream commit d37c120b73128690434cc093952439eef9d56af1 ]
While the interface for the MMU mapping takes phys_addr_t to hold a full 64bit address when necessary and MMUv2 is able to map physical addresses with up to 40bit, etnaviv_iommu_map() truncates the address to 32bits. Fix this by using the correct type.
