usb: dwc_otg_310: Prevent phy access if not probed.

In case the PHY is not successfully probed, we cannot
access PHY functions like usb20otg_hw_init(), because
they assume successful probing and might dereference
NULL pointers otherwise.

This patch addresses this by introducing a flag 'is_probed',
which can be checked during controller probing time to
verify, that the PHY has been probed.
If this was not the case, controller probing will be deferred.
