wls: add power boost logic

Browse source 
Just as the commit of https://gerrit.mot.com/#/c/2239737/
CPS4019 is just powered by AC/VOUT. So if VBUS is low,
CPS4019 do not have power source. We have to use OTG
bootst from charger IC to get the power. So we should add
power boost trigger operation before FW checking logic.
