Added missing __iomem annotation and staticized local symbols
in order to fix the following sparse warnings:

drivers/mtd/maps/cfi_flagadm.c:58:17: warning: symbol 'flagadm_map' was not declared. Should it be static?
drivers/mtd/maps/cfi_flagadm.c:64:22: warning: symbol 'flagadm_parts' was not declared. Should it be static?
drivers/mtd/maps/cfi_flagadm.c:115:18: warning: cast removes address space of expression
drivers/mtd/maps/cfi_flagadm.c:115:18: warning: incorrect type in argument 1 (different address spaces)
drivers/mtd/maps/cfi_flagadm.c:115:18:    expected void volatile [noderef] <asn:2>*addr
drivers/mtd/maps/cfi_flagadm.c:115:18:    got void *<noident>
