powerpc/44x: Add MTD support (NOR FLASH) to Katmai dts
This patch adds NOR FLASH MTD support to the Katmai (440SPe) dts file. For this the OPB ranges address is mapped differently (base 0x00000000 -> 0xe0000000). This results in the address being identical to the lower 32bit of its physical address. This is needed for the MTD mapping to work correctly, since U-Boot will insert the physical addresses of the EBC chip selects into the EBC ranges property. This is the way its done in most other 4xx dts files as well. Additionally with a small whitespace cleanup.
