soc: renesas: rcar-rst: Fix __iomem on configure call

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

    drivers/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
