Tomasz Bursztyka fea1c49ba2 gpio: Improve the public API to handle multi callbacks
Many sub-systems might require to set a callback on different pins.
Thus enabling it via changing the API.

It is also possible to retrieve private-data in the callback handler
using CONTAINER_OF() macro (include/misc/util.h).

Former API is still available, and is emulated through the new one.
Using both should not be a problem as it's using new API calls.
However, it's now better to start using the new API.

Looking at all structs as to where we can pack them a little better, and
calling out the padding/stride at the end for future expansion.
