Print the name of the DRM driver when taking over fbdev devices. Makes
the output to dmesg more consistent. Note that the driver name is only
used for printing a string to the kernel log. No UAPI is affected by this
change.

The field drm_device.irq_enabled is only used by legacy drivers
with userspace modesetting. Don't set it in armada.

All they do is refcount the fb, which the atomic helpers already do.

This is was necessary with the legacy helpers and I guess just carry
over in the conversion. drm_plane_state always has a full reference
for its -&gt;fb pointer during its entire lifetime,
see __drm_atomic_helper_plane_destroy_state()

Many drivers reference the plane-&gt;state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.

Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.

This was made using the coccinelle script below:

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.

The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.

Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.

all the drivers.

Some drivers are storing the plane-&gt;state pointer in atomic_update and
atomic_disable in a variable simply called state, while the state passed
as an argument is called old_state.

In order to ease subsequent reworks and to avoid confusing or
inconsistent names, let's rename those variables to new_state.

This was done using the following coccinelle script, plus some manual
changes for mtk and tegra.
