[ARM] pxa/income: Add Income SBC support
This is support for custom design based on Toradex Colibri PXA270 CPU card. Initial patch was by Pavel Revak. [daniel - rebased the code to follow the module/board split] Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Cc: Pavel Revak <palo@bielyvlk.sk> Cc: Daniel Mack <daniel@caiaq.de> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
