extcon_set_property_capability() just sets the capability
of EXTCON_PROP_USB_TYPEC_POLARITY property.

If you want to set the value (0 or 1) of EXTCON_PROP_USB_TYPEC_POLARITY,
we have to call extcon_set_property() function. But, this patch doesn't
set the any value of EXTCON_PROP_USB_TYPEC_POLARITY property.

Why do you only use extcon_set_property_capability()
without the proper extcon_set_property()?
