ANDROID: Drop out of tree leftovers in drivers: pinctrl

The patch "FROMLIST: drivers: pinctrl: msm: setup GPIO chip in
hierarchy" got an equivalent change merged upstream. The merged version
upstream differs from our version.

Based on the comment in
https://lore.kernel.org/lkml/20191113183506.GA18786@codeaurora.org/, we
can drop this difference.

See the leftover patch here:
https://android.googlesource.com/kernel/common-patches/+/9df68ac052d13e6e5035d8c131a51cf55eb78c99/android-mainline/FROMLIST-drivers-pinctrl-msm-setup-GPIO-chip-in-hierarchy.patch
This we can drop with this merged.
