The requirements_met variable was used to track two things: enabled
CRTCs and the power well. After the latest chagnes, we get a runtime
PM reference whenever we get any of the power domains, and we get
power domains when we enable CRTCs or the power well, so we should
already be covered, not needing this specific tracking.

Currently, when our driver becomes idle for i915.pc8_timeout (default:
5s) we enable PC8, so we save some power, but not everything we can.
Then, while PC8 is enabled, if we stay idle for more
autosuspend_delay_ms (default: 10s) we'll enter runtime PM and put the
graphics device in D3 state, saving even more power. The two features
are separate things with increasing levels of power savings, but if we
disable PC8 we'll never get into D3.

While from the modularity point of view it would be nice to keep these
features as separate, we have reasons to merge them:
 - We are not aware of anybody wanting a "PC8 without D3" environment.
 - If we keep both features as separate, we'll have to to test both
   PC8 and PC8+D3 code paths. We're already having a major pain to
   make QA do automated testing of just one thing, testing both paths
   will cost even more.
 - Only Haswell+ supports PC8, so if we want to add runtime PM support
   to, for example, IVB, we'll have to copy some code from the PC8
   feature to runtime PM, so merging both features as a single thing
   will make it easier for enabling runtime PM on other platforms.

This patch only does the very basic steps required to have PC8 and
runtime PM merged on a single feature: the next patches will take care
of cleaning up everything.

The name 'update_plane' was used both for the primary plane functions in
intel_display.c and the sprite/overlay functions in intel_sprite.c.
Rename the primary plane functions to 'update_primary_plane' to avoid
confusion.

On a similar note, intel_display.c already had a function called
intel_disable_primary_plane() that programs the hardware to disable a
pipe's primary plane.  When we hook up primary planes through the DRM
plane interface, one of the natural handler names will be
intel_primary_plane_disable(), which is very similar.  To avoid
confusion, rename the existing intel_disable_primary_plane() to
intel_disable_primary_hw_plane() to make the two names a little more
distinct.

The TP_printk() should never dereference any pointers, because the ring
buffer can be read at some unknown time in the future. If a device no
longer exists, it can cause a kernel oops. This also makes this
event useless when saving the ring buffer in userspaces tools such as
perf and trace-cmd.

The i915_gem_evict_vm dereferences the vm pointer which may also not
exist when the ring buffer is read sometime in the future.

The reordered setup sequence ended up calling del_timer_sync before
the timer was set up correctly, resulting in endless hilarity when
loading the driver.

Compared to Ben's patch (which moved around the setup_timer call to
sanitize_early) this moves the sanitize_early call around in the
driver load call. This way we avoid calling setup_timer again in the
resume code (where we also call sanitize_early).

Let the drivers specify the name of the I2C-over-AUX adapter to maintain
backwards compatibility in the sysfs when converting to the new
I2C-over-AUX helper infrastructure.

The i915 driver currently uses DPDDC-A to DPDDC-D as names for the DP
i2c adapters. These names show up in the i2c sysfs name attribute. We'd
like to be able to maintain that when switching over to the new helpers.

Due to i2c device and connector cleanup ordering issues we also recently
made the drm device (instead of connector) the parent of the i2c
adapters:
