[PATCH 1/2] MTD: autcpu12-nvram: Fix compile breakage

Update driver autcpu12-nvram.c so it compiles. map_read32/map_write32 no
longer exist in the kernel so the driver is totally broken.
Additionally, map_info name passed to simple_map_init is incorrect.

CC drivers/mtd/maps/autcpu12-nvram.o
drivers/mtd/maps/autcpu12-nvram.c: In function 'init_autcpu12_sram':
