irqchip: renesas-h8s: Replace ctrl_outw/ctrl_inw with writew/readw

Commit 13ae42a3b1c1 ("h8300: Rename ctlr_out/in[bwl] to
raw_read/write[bwl]") changed the function names, but not all callers,
resulting in

drivers/irqchip/irq-renesas-h8s.c: In function ‘h8s_disable_irq’:
drivers/irqchip/irq-renesas-h8s.c:43:9: error:
	implicit declaration of function ‘ctrl_inw’
drivers/irqchip/irq-renesas-h8s.c:44:2: error:
	implicit declaration of function ‘ctrl_outw’

Fixes: 13ae42a3b1c1 ("h8300: Rename ctlr_out/in[bwl] to raw_read/write[bwl]")
