gpio: samsung: Remove legacy support of S5PV210
Browse files Browse the repository at this point in the history 
GPIO support of S5PV210 SoC is now fully handled by pinctrl-samsung
driver making the old code in gpio-samsung driver unused. This patch
removes it which will also let us remove more code from arch subtree.
