[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.
