da1469x: Fix no VBUS startup
For self powered device if device started without VBUS present
it would not be correctly attached to USB bus even if tusb_vbus_changed()
was later called.
This modifies dcd_init() so it starts USB state machine without checking
if VBUS is present or not, like all others drivers do.
tusb_vbus_changed() function is also removed its content was moved to dcd_init.
