Having the pin control framework call pin controller functions
before it's probe has finished is not nice as the pin controller
device driver does not yet have struct pinctrl_dev handle.

Let's fix this issue by adding deferred work for hogs. This is
needed to be able to add pinctrl generic helper functions.

Note that the pinctrl functions already take care of the necessary
locking.

I don't see why this is necessary?

It's needed because the pin controller driver has not yet
finished it's probe at this point. We end up calling functions
in the device driver where no struct pinctrl_dev is yet known
to the driver. Asking a device driver to do something before
it's probe is done does not quite follow the Linux driver model :)

To clarify, that's an issue with multiple instances of the same
driver probing as there's no static pointer to driver specific
data.

To clarify even more, the following patches in this series need
struct pinctrl_dev to pass to the generic functions :)
