ARM: dts: ixp4xx: Create a proper expansion bus

Browse source

The IXP4xx expansion bus is 24 bits (256 MB) that is memory
mapped between 0x50000000-0x5fffffff usin a set of chip
selects. The size of the windows is 16 or 32MB defined by
the boot loader system configuration at runtime.

Create a rudimentary simple-bus and move the flash memories
to the expansion bus, inside the SoC.
