extcon: Simplify extcon_dev_register() prototype by removing unnecessary parameter
This patch remove extcon_dev_register()'s second parameter which means the pointer of parent device to simplify prototype of this function. So, if extcon device has the parent device, it should set the pointer of parent device to edev.dev.parent in extcon device driver instead of in extcon_dev_register().
