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.

Add EEPROM notifiers
These help board level code by allowing a callback when EEPROMs are
loaded, this permits system level configuration to be loaded from the
EEPROM. This is particularly useful when the ethernet MAC ids are
stored in EEPROM and when the ethernet hardware is generic (so it
has no board level knowledge), then the MACs can be loaded into
the 'maclist' code and read out by the ethernet config.
