The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might be not relevant here).  This
fixes compile warning (!CONFIG_OF with clang):
    drivers/memory/ti-emif-pm.c:238:34: warning:
        unused variable 'ti_emif_of_match' [-Wunused-const-variable]
