[ARM] 4033/1: Add separate Avila board setup code

This patch adds support for the Gateworks Avila Network Platform in
a separate set of setup files to the IXDP425. This is necessary now
that a driver for the Avila CF card slot is available. It also adds
support for a minor variant on the Avila board known as the Loft,
which has a different number of maximum PCI devices.
