Yang Yingliang 5ed0519d42 pinctrl: renesas: core: Fix possible null-ptr-deref in sh_pfc_map_resources() 
[ Upstream commit 5376e3d904532e657fd7ca1a9b1ff3d351527b90 ]

It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

Fixes: c7977ec4a336 ("pinctrl: sh-pfc: Convert to platform_get_*()")
