powerpc/85xx: add alternate dts file for sbc8548 boot via SODIMM
By moving the two JP12 jumpers 90 degrees, and switching the
setting of SW2.8, the sbc8548 can be configured to boot off
the alternate 64MB SODIMM, which when populated with u-boot
can be a handy recovery option, in case the u-boot in the
8MB soldered on flash gets corrupted. Here we add an alternate
dts file to match that configuration.
To better highlight the differences, the output from the u-boot
"fli" command is shown for the normal configuration and then
the alternate configuration.
