gpu: host1x: Fix build for Linux v6.3

Browse Source 
Upstream Linux commit ("1369459b2e21 iommu: Add a gfp parameter to
iommu_map()") adds a new parameter to the iommu_map function and this
breaks building the host1x driver with Linux v6.3.

Upstream Linux commit 2a81ada32f0e ("driver core: make struct
bus_type.uevent() take a const *") updates the uevent function pointer
type to make the device structure const which also breaks building the
host1x driver with Linux v6.3.

Address both of these issues to fix building the host1x driver with
Linux v6.3.
