To support legacy gamma ioctls the drivers need to set
drm_crtc_funcs.gamma_set either to a custom implementation or to
drm_atomic_helper_legacy_gamma_set. Most of the atomic drivers do the
latter.
We can simplify this by making the core handle it automatically.
Move the drm_atomic_helper_legacy_gamma_set() functionality into
drm_color_mgmt.c to make drm_mode_gamma_set_ioctl() use
drm_crtc_funcs.gamma_set if set or GAMMA_LUT property if not.

The TXP so far has been leveraging the PixelValve infrastructure in the
driver, that was really two things: the interaction with DRM's CRTC
concept, the setup of the underlying pixelvalve and the setup of the shared
HVS, the pixelvalve part being irrelevant to the TXP since it accesses the
HVS directly.
Now that we have a clear separation between the three parts, we can
represent the TXP as a CRTC of its own, leveraging the common CRTC and HVS
code, but leaving aside the pixelvalve setup.

[airlied: fixed XA limit build breakage, Rodrigo also submitted the same patch, but
I squashed it in the merge.]

The global list of all debugfs entries for the driver was painful: the
list couldn't see into the components' structs, so each component had
its own debugs show function to find the component, then find the
regset and dump it. The components also had to be careful to check
that they were actually registered in vc4 before dereferencing
themselves, in case they weren't probed on a particular platform.
They routinely failed at that.
Instead, we can have the components add their debugfs callbacks to a
little list in vc4 to be registered at drm_dev_register() time, which
gets vc4_debugfs.c out of the business of knowing the whole list of
components.
Thanks to this change, dsi0 (if it existed) would register its node.
v2: Rebase on hvs_underrun addition.
v3: whitespace fixup

The drm_writeback_queue_job() function takes ownership of the passed job
and requires the caller to manually set the connector state
writeback_job pointer to NULL. To simplify drivers and avoid errors
(such as the missing NULL set in the vc4 driver), pass the connector
state pointer to the function instead of the job pointer, and set the
writeback_job pointer to NULL internally.
