typec: Fix COM charging failed when using audio 2-1 adapter

Browse source 
Using Type-C to 3.5mm Headphone 2-in-1 Adapter，COM charging Failed.
Because the devices are in off-mode when usb plug-in,bootup process might
cause some detection delay.
So when DUT power on with typec and the typec vbus is exist,we need to
wait some times for check type-c is connected before call
smb5_typec_attach_detach_irq_handler.
