media: renesas: rcar_drif: Drop of_match_ptr()

The device_driver structure's of_match_table field exists
unconditionally, so there's no need for of_match_ptr(). This fixes a
compiler warning when test-compiling on non-OF platforms:

drivers/media/platform/renesas/rcar_drif.c:1470:34: warning: unused variable 'rcar_drif_of_table' [-Wunused-const-variable]
static const struct of_device_id rcar_drif_of_table[] = {
                                 ^
