arm: pxa: Add support for ICP DAS LP-8x4x

LP-8x4x is a programmable automation controller by ICP DAS. It is
shipped with outdated U-Boot v1.3.0

This patch adds enough supports to boot the board:
 - 128M of 128M SDRAM
 - 32M of 48M NOR Flash memory
 - 1 of 4 Serial consoles (PXA FFUART)
 - 2 of 2 Ethernet controllers (DM9000)
