[PATCH 4.20 007/183] gpio: pxa: avoid attempting to set pin direction via pinctrl on MMP2

[Greg Kroah-Hartman]

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lubomir Rintel <lkundrak@xxxxx>

commit af14b2c98adb85e9517390bb88309338b9075350 upstream.

Similarly to PXA3xx, pinctrl-single can't set pin direction on MMP2 either.
See also: commit 9dabfdd84bdfa ("gpio: pxa: disable pinctrl calls for
PXA3xx")
