Add pin control support for lpass sc7280

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 V9:
    -- Add pinctrl groups macro to Kconfig.
Changes Since V8:
    -- Remove redundant headers included in v8.
Changes Since V7:
    -- Update optional clock voting with conditional check.
    -- Add const to lpi_pinctrl_variant_data structure.
    -- Update required headers and remove redundant.
    -- Change EXPORT_SYMBOL to EXPORT_SYMBOL_GPL
    -- Fix typo errors.
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.
