This patch series is to split lpass variant common pin control
functions and SoC specific functions and to add lpass sc7280 pincontrol support.
It also Adds dt-bindings for lpass sc7280 lpass lpi pincontrol.
Changes Since V6:
-- Update conditional clock voting to optional clock voting.
-- Update Kconfig depends on field with select.
-- Fix typo errors.
Changes Since V5:
-- Create new patch by updating macro name to lpi specific.
-- Create new patch by updating lpi pin group structure with core group_desc structure.
-- Fix typo errors.
-- Sort macros in the make file and configuration file.
Changes Since V4:
-- Update commit message and description of the chip specific extraction patch.
-- Sort macros in kconfig and makefile.
-- Update optional clock voting to conditional clock voting.
-- Fix typo errors.
-- Move to quicinc domain email id's.
Changes Since V3:
-- Update separate Kconfig fields for sm8250 and sc7280.
-- Update module license and description.
-- Move static variables to corresponding .c files from header file.
Changes Since V2:
-- Add new dt-bindings for sc7280 lpi driver.
-- Make clock voting change as separate patch.
-- Split existing pincontrol driver and make common functions
as part of separate file.
-- Rename lpass pincontrol lpi dt-bindings to sm8250 specific dt-bindings
Changes Since V1:
-- Make lpi pinctrl variant data structure as constant
-- Add appropriate commit message
-- Change signedoff by sequence.

dt-bindings: pinctrl: qcom: Update lpass lpi file name to SoC specific
dt-bindings: pinctrl: qcom: Add sc7280 lpass lpi pinctrl bindings
pinctrl: qcom: Update macro name to LPI specific
pinctrl: qcom: Update lpi pin group structure
pinctrl: qcom: Extract chip specific LPASS LPI code
pinctrl: qcom: Add SC7280 lpass pin configuration
pinctrl: qcom: Update clock voting as optional
Tested this on SM8250 MTP with WSA and WCD codecs.
