drm/imagination: Removed unused function to_pvr_vm_gpuva()

This function is now unused, hence it causes a compiler warning.

   drivers/gpu/drm/imagination/pvr_vm.c:112:22: warning: unused function 'to_pvr_vm_gpuva' [-Wunused-function]
     112 | struct pvr_vm_gpuva *to_pvr_vm_gpuva(struct drm_gpuva *gpuva)
         |                      ^

Remove the function for now.
