[ARM] 3334/1: Add support for IXDP28x5 platforms 

Patch from Deepak Saxena

This patch adds support for Intel's IXDP28x5 platform. This
is just and IXDP2801 with a new CPU rev but the bootloader
has been updated to reflect a new machine ID so we just build
support for it by default when we build IXDP2801.
