[PATCH] pinctrl: rza1: fix incorrect failure check on platform_get_resources

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

The return res from platform_get_resources should be checked for
a failure rather than ret.  Fixes warning:

'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]

Fixes: 5a49b644b307 ("pinctrl: Renesas RZ/A1 pin and gpio controller")
