[PATCH v2 1/5] extcon: Make the allocation and freeing to be private calls

[Andy Shevchenko]

The extcon_dev_allocate() and extcon_dev_free() are not used
outside of the extcon framework. Moreover, the struct extcon_dev
can't be filled outside of the framework either after allocation.
The registration part, for instance, requires a parent device to
be set and that's done in the devm_extcon_dev_allocate() wrapper.

Taking the above into account, sumply move the mentioned APIs to
the private headers.

Alternatively, the pointer to the parent device can be added to
the extcon_dev_allocate(), but since there are no users and magnitude
of the change it makes a little sense to go this way.
