[ARM] pxa/em-x270: prepare addition of eXeda machine to em-x270.c
Change several GPIO assignment from static to run-time Split MFP table to common and EM-X270 specific parts Introduce em_x270_module_init Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Eric Miao <eric.miao@marvell.com>
