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: 4185b27b3bef ("dt-bindings: clock: Add YAML schemas for LPASS clocks on SC7280").

The clock gating control for TX/RX/WSA core bus clocks would be required
to be reset(moved from hardware control) from audio core driver. Thus
add the support for the reset clocks.
Also add the external mclk to interface external MI2S.
Fixes: a9dd26639d05 ("clk: qcom: lpass: Add support for LPASS clock controller for SC7280").
