[PATCH v2 0/6] Support render only drivers

[Frank Binns]

This series resurrects work originally done by Thierry Reding (hence
the v2) but without taking things quite as far as the original [1].

The motivation for this series is to remove the dual meaning of
the DRIVER_MODESET feature flag, whereby it means "support kernel
modesetting" and "don't expose pre-KMS legacy behaviour". Without
this, it's necessary for render only drivers, such as etnaviv, to
choose between falsely advertising themselves as modesetting drivers
or exposing legacy behaviour. Unlike the original series, it doesn't
restrict the card-node to drivers that set DRIVER_MODESET.

As a couple of years have now passed, a number of the patches from the
original series have now either been merged (mainly clean up), are no
longer relevant or have no code changes in common with the originals.
It also means that some new patches are needed. Those patches that have
been rebased are marked as v2.
