usb: phy-msm-usb: Allow peripheral mode switch in more host states

The current code allows peripheral mode switch in only A_HOST state
using user mode otg control debug interface. The target can also be in
A_WAIT_BCON and A_SUSPEND while operating as a host. Allow peripheral mode
switch in these states as well. Also check the PMIC id status
when the otg control is set to PMIC.
