soc: qcom: eud: Update the state of extcon too during probe

If EUD is enabled by the bootloader, currently the kernel driver
only enables the interrupts. However, the USB/extcon will still
see that the cable is disconnected as the EUD driver doesn't set
an initial state. Hence, explicitly set the state of the USB
as 'true' (connected) if the driver's probe realises that EUD
is already enabled by the bootloader.
