[PATCH 0/3] serial: liteuart: fix compile testing and driver unbind

[Johan Hovold <johan@kernel.org>]

Ilia Sergachev noted that the liteuart remove() function would trigger a
NULL-pointer dereference if it was ever called since the driver data
pointer was never initialised.

Turns out there are more bugs in this part of the driver which clearly
has never been tested.

Also fix up the Kconfig dependencies so that the driver can actually be
compile tested.

Note that this series depends on the fix by Ilia:
