[PATCH] drm/etnaviv: fix '%x' warning

[Gustavo A. R. Silva]

Fix the following warning by using %zx instead of %x for variable of
type size_t:

warning: format ‘%x’ expects argument of type ‘unsigned int’, but
argument 4 has type ‘size_t {aka long unsigned int}’ [-Wformat=]

Fixes: 50073cf98d16 ("drm/etnaviv: mmu: stop using iommu map/unmap functions")
