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)
                    ^~~~~~~~~~~~~~~~

             ^~~~~~~~~~~~~~~~
Move them to #ifdef CONFIG_OF block to fix this.
