mtd: maps: sc520cdp: fix warnings
On m86k, and maybe a few other architectures, we get this kind of
warning, due to misuse of volatile:
drivers/mtd/maps/sc520cdp.c: In function 'sc520cdp_setup_par':
>> drivers/mtd/maps/sc520cdp.c:223:2: warning: passing argument 1 of 'iounmap' discards 'volatile' qualifier from pointer target type [enabled by default]
arch/m68k/include/asm/raw_io.h:22:13: note: expected 'void *' but argument is of type 'volatile long unsigned int *'
Rather than annotating the variable declaration, let's just use the
proper accessors, which add the 'volatile' qualifier to the operation.
