[ 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.
Fixes: 931e97f3afd8 ("drm/etnaviv: mmuv2: support 40 bit phys address")
