[PATCH -next v2] pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data()

[Wei Yongjun <weiyj.lk@gmail.com>]

From: Wei Yongjun <weiyongjun1@huawei.com>

In case of error, the function devm_ioremap() returns NULL pointer not
ERR_PTR(). Fix by using devm_ioremap_resource instead of devm_ioremap.

Fixes: 8b1bd11c1f8f ("pinctrl: samsung: Add the support the multiple
IORESOURCE_MEM for one pin-bank")
