USB: dwc3-msm: Fix LPM related issues with FLOATED charger connected
Currently dwc3-msm driver is putting HSPHY into RETENTION apart from
voting for VDD minimization when FLOATED charger is connected. This
results in spurious MPM interrupt getting triggered during system
suspend. Due to this, charger detection will be performed endlessly
in case of FLOATED charger. Hence don't put HSPHY into RETENTION with
FLOATED charger connected and also fix bug in incrementing charger
retry count.
