[PATCH v4 1/4] dt-bindings: clock: airoha: Add reset support to EN7581 clock binding

[Lorenzo Bianconi]

Introduce reset capability to EN7581 device-tree clock binding
documentation. Add reset register mapping between misc scu and pb scu
ones in order to follow the memory order. This change is not
introducing any backward compatibility issue since the EN7581 dts is not
upstream yet.
