arm64: dts: mesong12_odroid_common: Set extcon state for dwc2_a cable as always true

Since this, extcon state for dwc2_a, dwc_otg udc becomes always
'USB=1'.

Note: odroid-c4/n2 connects usb_dwc2_a_id to usb connector id
and usb_dwc2_a_vbus to usb connector vbus, so usb connect event
can be detected including otg host and peripheral recognition.
But the detection is possible to after configuration gadget on
the udc, so in Tizen, it does not work because Tizen deviced
waits usb connection to configure gadget on the udc. Because of
this constraint in Tizen deviced, as a workaround, set extcon
state for dwc2_a usb cable as connected.
