Paul Gortmaker d5bc813f40 powerpc/85xx: enable MTD options in sbc8548 defconfig 
This board has soldered on flash, and a SODIMM flash module.
Both can be used for booting, via switching JP12 and SW2.8
and using the sbc8548-altflash.dts when booting from SODIMM.

Here we enable MTD in kernel so that we can see the bootloader
(and other flash sectors) from linux.

Normal configuration:

 root@sbc8548:~# cat /proc/mtd
 dev:    size   erasesize  name
 mtd0: 007a0000 00020000 "space"
 mtd1: 00060000 00020000 "bootloader"
 mtd2: 03f00000 00080000 "space"
 mtd3: 00100000 00080000 "bootloader"

Note that in the latter, the larger SODIMM device appears 1st,
as mtd0 and mtd1, as indicated in the sizes, and in the date
of the u-boot image.

The kernel configuration is the same in both cases; only the dtb
needs to be changed in accordance with the JP12/SW2.8 settings.
