usb: phy: Skip phy init when eud is connected 



Currently phy driver us initializing phy irrespective
of eud connected or not. But driver shouldn't re-init
the phy if eud is connected since it can break eud
functionality once driver powerdown the phy and perform
re-initialization. Prevent this by bailing out early from
phy_init if eud_connected is set to true.
