usb: ehci-msm: Add init_after_reset for CI_UDC
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. Signed-off-by: Ramon Fried <ramon.fried@gmail.com>
