[PATCH 2/4] Add localbus node and MTD partitions for SBC834x

From: Liang Li <liang.li at windriver.com>

There is 8MB flash, 8kB EEPROM and 128MB SDRAM on the sbc834x
local bus, so add a localbus node in DTS with MTD partitions.

The recent U-boot commit fe613cdd4eb moves u-boot to the beginning
of flash, hence the legacy label on the partition at the end of flash.
