Subject: [PATCH v3 0/6] clk: qcom: sc8280xp: add lpasscc reset control

On SC8280XP, LPASS IP is controlled by q6dsp, however the reset lines
required by some of the IPs like Soundwire still need to be programmed from
Apps processor. This patchset adds support to reset controller on LPASS
CC and LPASS AudioCC.

Tested on X13s.

Thanks,
Srini

Changes since v2:
	- removed qcom,adsp-pil-mode bindings, can be added when
	 we have a variant of this SoC without dsp control
	- added compile check in Kconfig
	- fix variable naming to reflect correct cc.
	- few minor style related changes
