usb: ehci-msm: Add init_after_reset for CI_UDC

Browse Source 
MSM uses the chipidea controller IP, however it requires
to reinit the phy after controller reset. in EHCI mode there's a
dedicated callback for it.
In device mode however there's no such callback.
Add implementaion of ci_init_after_reset() to implement the above
requirement in case CI_UDC driver is used.
