phy: rockchip-inno-usb2: fix dwc2 init failed due to core soft reset

Browse Source 
timeout

Dwc2 controller will call phy init function during probe, Current code
will schedule otg_sm_work immediately after phy init, if we don't plug
in usb cable at this time, phy will power off soon after, this will
cause dwc2 do core soft reset failed.

To resolve this problem, We use typec_vbus_det property to distinguish
whether otg_sm_work needs to be executed immediately, If not needed,
delay 1 second.
