ARM: shmobile: lager: Enable SCIF0 and SCIF1 serial ports in DT
SCIF0 and SCIF1 are used as debug serial ports. Enable them and configure pinmuxing appropriately. We can now remove the clkdev registration hack for SCIF devices from the Lager reference board file. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> [horms+renesas@verge.net.au: updated changelog to remove references to device renaming] [horms+renesas@verge.net.au: resolved conflicts] Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
