This patch adds support for LPASS (Low Power Audio SubSystem)
LPI (Low Power Island) pinctrl on SM8250.

This patch has been tested on support to Qualcomm Robotics RB5 Development
Kit based on QRB5165 Robotics SoC. This board has 2 WSA881X smart speakers
with onboard DMIC connected to internal LPASS codec via WSA  and VA macros
respectively.

Most of the work is derived from downstream Qualcomm kernels.
Credits to various Qualcomm authors from Patrick Lai's team who have
contributed to this code.

Changes since v1:
	- updated bindings to use '-pins$' instead of wild card matching as
	 suggested by Rob.
