Subject[PATCH] gpu: host1x: Fix compiler errors
The compiler is complaining with the following errors:

drivers/gpu/host1x/cdma.c:94:48: error:
passing argument 3 of ‘dma_alloc_wc’ from incompatible pointer type
[-Werror=incompatible-pointer-types]

drivers/gpu/host1x/cdma.c:113:48: error:
passing argument 3 of ‘dma_alloc_wc’ from incompatible pointer type
[-Werror=incompatible-pointer-types]

The expected pointer type of the third argument to dma_alloc_wc() is
dma_addr_t but phys_addr_t is passed. Fix this by adding casts to the
expected pointer type.
