drm/msm: Drop load/unload drm_driver ops
The load/unload drm_driver ops are deprecated. They should be removed as
they result in creation of devices visible to userspace even before
the drm_device is registered.
Drop these ops and use drm_dev_alloc/register and drm_dev_unregister/unref
to explicitly create and destroy the drm device in the msm platform
driver's bind and unbind ops. With this in use, the drm connectors are
only registered once the drm_device is registered.
It also fixes the issue of stray debugfs files after the msm module is
removed. With this, all the debugfs files are removed, and allows
successive module insertions/removals.
Move the drm_connector registration from the encoder(HDMI/DSI etc) drivers
to the msm platform driver. This will simplify the task of ensuring that
the connectors are registered only after the drm_device itself is
registered.
The connectors' destroy ops are made to use kzalloc instead of
devm_kzalloc to ensure that that the connectors can be successfully
unregistered when the msm driver module is removed. The memory for the
connectors is unallocated when drm_mode_config_cleanup() is called
during either during an error or during driver remove.

The MDP4 driver tries to request and set voltages for regulators required

regulator via DT and managed by the regulator core.

The voltage changing code in this driver is broken and should be
removed. The driver sets a single, exact voltage on probe. Unless
there is a very good reason for this (which should be documented in
comments) constraints like this need to be set via the machine
constraints, voltage setting in a driver is expected to be used in cases
where the voltage varies at runtime.
In addition client drivers should almost never be calling
regulator_can_set_voltage(), if the device needs to set a voltage it
needs to set the voltage and the regulator core will handle the case
where the regulator is fixed voltage. If the driver simply skips
setting the voltage if it doesn't have permission then it should just
not bother in the first place.
Originally authored by Mark Brown <broonie@kernel.org>
Remove the min/max voltage data entries per SoC managed by the driver.
These aren't needed as we don't try to set voltages any more. Mention in

drm/core: Do not preserve framebuffer on rmfb, v4.
It turns out that preserving framebuffers after the rmfb call breaks
vmwgfx userspace. This was originally introduced because it was thought
nobody relied on the behavior, but unfortunately it seems there are
exceptions.
drm_framebuffer_remove may fail with -EINTR now, so a straight revert
is impossible. There is no way to remove the framebuffer from the lists
and active planes without introducing a race because of the different
locking requirements. Instead call drm_framebuffer_remove from a
workqueue, which is unaffected by signals.
