[PATCH v2 2/2] pinctrl: qcom: sc7280: Add lpi pinctrl variant data for adsp based targets

[Srinivasa Rao Mandadapu <quic_srivasam@xxxxxxxxxxx>]

Add compatible string and lpi pinctrl variant data structure for adsp
enabled sc7280 platforms.
This variant data structure rnd compatible name required for
distingushing ADSP based platforms and ADSP bypass platforms.
In case of ADSP enabled platforms, where audio is routed through ADSP
macro and decodec GDSC Switches are triggered as clocks by pinctrl
driver and ADSP firmware controls them. So It's mandatory to enable
them in ADSP based solutions.
In case of ADSP bypass platforms clock voting is optional as these macro
and dcodec GDSC switches are maintained as power domains and operated from
lpass clock drivers.
