Subject: pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data()

pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data()

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")
