USB: phy-msm: Put PHY into SIDDQ for wall charger during bootup 



Currentlty USB driver is not putting PHY into SIDDQ with wall charger
connected during bootup and also not allowing VDD minimization even though
SMB hardware does charger detection. Hence fix this by making change
for proper dcp condition in suspend callback.
