Subject: [PATCH 1/5] dt-bindings: clock: mediatek,mt7622-pciesys: Remove syscon compatible

The PCIESYS register space contains a pure clock controller, which
has no system controller register, so this definitely doesn't need
any "syscon" compatible.

As a side note, luckily no devicetree ever added the syscon string
to PCIESYS clock controller node compatibles, so this also resolves
a dtbs_check warning for mt7622.
