4xx next branch updated

[Josh Boyer]

Hi all,

I've rebased the next branch of the 4xx tree to Ben's next branch, and added
the following commits:

Solomon Peachy (1):
      powerpc/40x: Add support for the ESTeem 195E (PPC405EP) SBC

Stefan Roese (2):
      powerpc/44x: Update Arches dts
      powerpc/44x: Update Arches defconfig

fkan at amcc.com (1):
      powerpc/44x: Add Eiger AMCC (AppliedMicro) PPC460SX evaluation board

I'm waiting for a couple more patches, then I'll ask Ben to pull.
