extcon: Add the support for the capability of each property
This patch adds the support of the property capability setting. This function
decides the supported properties of each external connector on extcon provider
driver.
Ths list of new extcon APIs to get/set the capability of property as following:
- int extcon_get_property_capability(struct extcon_dev *edev,
unsigned int id, unsigned int prop);
- int extcon_set_property_capability(struct extcon_dev *edev,
unsigned int id, unsigned int prop);
