Fri Dec 15 16:23:02 PST 2023
Add various clock controllers found in the MT7988 SoC to existing
bindings (if applicable) and add files for the new ethwarp, mcusys
and xfi-pll clock controllers not previously present in any SoC.

v6:
* remove invalid '_' from compatible string
* drop minItems where uneeded due to listed clock-names
* fix condition regarding presence of the 'pcs' subnode
v5:
* drop use of ti,syscon-reset and hence also syscon and simple-mfd
compatibles from mt7988-ethwarp clock controller which now got the
clock controller provide the reset(s).
v4:
* add subnodes for controllers acting as MFD
v3:
* move clock bindings to clock folder
* drop ti,syscon-reset from bindings and example
* merge mcusys with topckgen bindings
v2:
* dropped unused labels
* add 'type: object' declaration for reset-controller found in new
ethwarp controller and represented as ti,syscon-reset
* rebase on top of
