pinctrl: qcom: sc7280: Add clock optional check for ADSP bypass targets

Browse Source 
Update lpass lpi pin control driver, with clock optional check for ADSP
disabled platforms. This check 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.
