The MediaTek MT7981 SoC is the smaller sibbling of the MT7986 SoC.
While MT7986 is already fully supported in vanilla Linux, only few things
are missing to support also MT7981.

Add pinctrl driver including devicetree bindings for MediaTek MT7981
which together with the added clock drivers[1] completes support for the
most basic features of this SoC.

A complete work-in-progress tree based on linux-next for testing is
available via Github[2]:

Changes since v1:
 * cleaned up YAML bindings according to comments of Rob Herring
 * sync with pinctrl-mt7986.c to get pu/pd bias working

Bindings reviewed, the driver is vert straight-forward and slim, and
no further comments, so patches applied for v6.3.
