pinctrl: samsung: Fix memory mapping code
Some pinctrls share memory regions, and devm_ioremap_resource does not
allow to share resources, in opposition to devm_ioremap.
This patch restores back usage of devm_ioremap function, but with proper
error handling and logging.
Fixes: baafaca ("pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data()")
