202b1f4c12 drm/i915/gt: Move engine registers to their own header 
Let's continue breaking up and cleaning up the massive i915_reg.h file
by moving all registers that are defined in relation to an engine base
to their own header.

There are probably a bunch of other "engine registers" that we haven't
moved yet (especially those that belong to the render engine in the
0x2??? range), but this is a relatively straightforward first step.

2b25a93bf0 drm/i915: Introduce i915_reg_defs.h 
We'd like to start splitting i915_reg.h into various domain-specific
register files and cleaning them up.  Let's move the basic macros and
type definitions to their own header file that can be including in each
of the new split headers.

637088a21e drm/i915/backlight: Make ext_pwm_disable_backlight() call intel_backlight_set_pwm_level() 
At least the Bay Trail LPSS PWM controller used with DSI panels on many
Bay Trail tablets seems to leave the PWM pin in whatever state it was
(high or low) ATM that the PWM gets disabled. Combined with some panels
not having a separate backlight-enable pin this leads to the backlight
sometimes staying on while it should not (when the pin was high during
PWM-disabling).

First calling intel_backlight_set_pwm_level() will ensure that the pin
is always low (or high for inverted brightness panels) since the passed
in duty-cycle is 0% (or 100%) when the PWM gets disabled fixing the
backlight sometimes staying on.

With the exception of ext_pwm_disable_backlight() all other
foo_disable_backlight() functions call intel_backlight_set_pwm_level()
already before disabling the backlight, so this change also aligns
ext_pwm_disable_backlight() with all the other disable() functions.

The funcs struct can be opaque, make it internal to intel_cdclk.c.

cce936f4ff drm/i915/cdclk: turn around i915_drv.h and intel_cdclk.h dependency 
intel_cdclk.h only needs i915_drv.h for struct intel_cdclk_config. Move
the definition to intel_cdclk.h and turn the includes around to avoid
including i915_drv.h from other headers.

The intel cdclk state macros in intel_cdclk.h still reference struct
drm_i915_private, but as macros they don't strictly require the
definition until they are used.

v2: Expand on the commit message wrt cdclk state macros

96db14432d drm/i915: Fix implicit use of struct pci_dev 
intel_device_info.h references struct pci_dev but does not ensure that
the struct has been declared, causing build failures if something in
other headers changes so that the implicit dependency it is relying on
is no longer satisfied:

6678916dfa drm/i915: Move pipe/transcoder/abox masks under intel_device_info.display 
Collect the dipslay related mask under the display sub-structure
in intel_device_info.

Note that there is a slight change in behaviour in that we zero
out .display entirely when !HAS_DISPLAY (aka. pipe_mask==0), so
now we also zero out the other masks (although cpu_transocder_mask
should already be zero of pipe_mask is zero). abox_mask is
only used by the display core init when HAS_DISPLAY is true, so
the actual behaviour of the system shouldn't change despite the
zeroing of these masks.

There is a lot more display stuff directly in device info that
could be moved over. Maybe someone else will be inspired to do it...
