[ARM] 5103/2: CM-X270: update core platform support
Convert CM-X270 pin configuration to use MFP tables. Make device initialization dependent on respective driver CONFIG_ value (like in zylonite). Cleanup includes Signed-off-by: Mike Rapoport <mike@compulab.co.il> Acked-by: Eric Miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
