Subject: [PATCH 0/4] pinctrl: meson: fix pull bits

This patchset fixes the inversion between pull (up/down) and pull enable
bits on the GPIO AO bank of all amlogic when have, except the axg family.

The problem has been found while testing bias setting on the libretech
aml-s905x-cc on GPIO_AO 5. Unfortunately the bias register of this bank is
not described in the public datasheet of the s905x, but it is in the
one of the A113D, which gave a clue.

This was tested on gxl libretech aml-s905x-cc. Since all Amlogic we have
got so far derive from each other, there is no reason for things to be
any different on the meson8(b).

I would have preferred to make a single patch to fix this but the commit
introducing the mistake the is different for each SoC, so a single patch
could be more difficult/annoying to backport.
