Subject: [PATCH v7 3/5] dt-bindings: clock: mediatek: add clock controllers
 of MT7988

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.

v7:
 * fix wrong path in $id of mediatek,mt7988-xfi-pll.yaml and
   mediatek,mt7988-ethwarp.yaml

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
   "dt-bindings: arm: mediatek: move ethsys controller & convert to DT schema"
