powerpc: update sbc8548 flash/mtd settings

The sbc8548 dts information for flash was out of date with respect to u-boot configuration changes made just over a year ago. However MTD support wasn't enabled by default, so the stale information wasn't really an issue.

Here we update that information, split the dts file to allow sharing the common blocks between the two possible flash mappings, add the second mapping for when the jumpers are configured for booting off alternate flash, and add the necessary MTD settings to the defconfig, so that ease of use out of the box is improved.

Thanks,
Paul
