clk: qcom: lpass: Add support for resets & external mclk for SC7280

Browse source

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.

Update the lpass_aon_cc_main_rcg_clk_src ops to park the RCG at XO after
disable as this clock signal is used by hardware to turn ON memories in
LPASS. Also add the external mclk to interface external MI2S.
