[RFC][PATCH 2/3] usb: phy: msm: notify charger when power supply is unplugged

[Damien Riegel]

With the current code, msm_otg_notify_charger doesn't get called when a
power supply identified as a DCP is unplugged. To work around that,
update charger info and call the notify function when switching from
idle to host.
