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 It is shipped with outdated U-Boot v1.3.0 This patch adds enough supports to boot the board: - 128M of 128M SDRAM - 32M of 48M NOR Flash memory - 1 of 4 Serial consoles (PXA FFUART) - 2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) Signed-off-by: Sergey Yanovich <ynvich@gmail.com> Series-to: u-boot Series-cc: marex
