The existing uAPI documentation does not adequately describe how the kernel
handles the case where the underlying hardware or driver does not support
the requested configuration.
Add a Configuration Support section describing that behaviour to both the
v1 and v2 documentation, and better document the errors returned where the
requested configuration cannot be supported.

Add documentation for the GPIO character device userspace API.
Added to the userspace-api book, but also provide a link from the
admin-guide book, as historically the GPIO documentation has been
there.
