Subject: [PATCH v2 1/3] dt-bindings: clock: Add resets for LPASS audio clock controller for SC7280

Add support for LPASS audio clock gating for RX/TX/SWA core bus clocks
for SC7280. Update reg property min/max items in YAML schema.

Fixes: 57405b795504 ("dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280").
