ixp4xx: update Gateworks Avila board support
Several new features for newer boards: - add additional UARTs present on some boards - add additional LEDs present on some boards - add HSS audio device codec present on some boards - add support for GSC present on some boards - add per model setup support for newer boards - set FLASH window per-model for boards with larger FLASH Some fixes: - add IRQ mapping for additional PCI devices (USB Host) Signed-off-by: Tim Harvey <tharvey@gateworks.com> SVN-Revision: 33647
