[PATCH] soc: renesas: rcar-rst: fix __iomem on configure call

["Ben Dooks (Codethink)" <ben.dooks@codethink.co.uk>]

The configure call back takes a register pointer, so should
have been marked with __iomem. Add this to silence the
following sparse warnings:

rivers/soc/renesas/rcar-rst.c:33:22: warning: incorrect type in initializer (incompatible argument 1 (different address spaces))
drivers/soc/renesas/rcar-rst.c:33:22:    expected int ( *configure )( ... )
drivers/soc/renesas/rcar-rst.c:33:22:    got int ( * )( ... )
drivers/soc/renesas/rcar-rst.c:97:40: warning: incorrect type in argument 1 (different address spaces)
drivers/soc/renesas/rcar-rst.c:97:40:    expected void *base
drivers/soc/renesas/rcar-rst.c:97:40:    got void [noderef] <asn:2> *[assigned] base
