[PATCH 13/29] pinctrl: mediatek: fix the return value in driving configuration functions

[Weijie Gao]

The original mediatek pinctrl functions for driving configuration
'mtk_pinconf_drive_set_*' do not return -ENOSUPP even if input
parameters are not supported.
This patch fixes the return value in those functions.
