Subject: [PATCH v2 -next] memory: omap-gpmc: Fix -Wunused-function warnings

If CONFIG_OF is not set, make W=1 warns:

drivers/memory/omap-gpmc.c:987:12: warning: ‘gpmc_cs_remap’ defined but not used [-Wunused-function]
 static int gpmc_cs_remap(int cs, u32 base)
            ^~~~~~~~~~~~~
drivers/memory/omap-gpmc.c:926:20: warning: ‘gpmc_cs_get_name’ defined but not used [-Wunused-function]
 static const char *gpmc_cs_get_name(int cs)
                    ^~~~~~~~~~~~~~~~
drivers/memory/omap-gpmc.c:919:13: warning: ‘gpmc_cs_set_name’ defined but not used [-Wunused-function]
 static void gpmc_cs_set_name(int cs, const char *name)
             ^~~~~~~~~~~~~~~~
Make them as  __maybe_unused to fix this.
