mtd: physmap_of_gemini: remove extranous __xipram annotation

Marking a local variable as __xipram causes a warning because of the
noinline attribute:

drivers/mtd/maps/physmap-gemini.c:89:11: error: '__noinline__' attribute only applies to functions [-Werror,-Wignored-attributes]
        map_word __xipram ret;
                 ^
include/linux/mtd/xip.h:34:18: note: expanded from macro '__xipram'
 #define __xipram noinline __attribute__ ((__section__ (".xiptext")))

I can't see any reason for the anotation anyway, so just remove it here.
