If the device does not have an aperture through which we can indirectly
access and detile the buffers, simply reject the ioctl. Later we can
extend the ioctl to support different modes, but as an extension the
user must opt in and explicitly control the mmap type (viz
MMAP_OFFSET_IOCTL).

Since CNP it's possible for rawclk to have two different values, 19.2
and 24 MHz. If the value indicated by SFUSE_STRAP register is different
from the power on default for PCH_RAWCLK_FREQ, we'll end up having a
mismatch between the rawclk hardware and software states after
suspend/resume. On previous platforms this used to work by accident,
because the power on defaults worked just fine.

Update the rawclk also on resume. The natural place to do this would be
intel_modeset_init_hw(), however VLV/CHV need it done before
intel_power_domains_init_hw(). Thus put it there even if it feels
slightly out of place.

v2: Call intel_update_rawclck() in intel_power_domains_init_hw() for all
    platforms (Ville).

After the reset, we do another clflush before checking the CSB to be
sure we see whatever was left in the CSB prior to the reset. So it is
unlikely to be an incoherent view of the CSB, and more likely that
Icelake didn't reset its pointers.

We then need to differentiate between suspend targets, to distinguish S0

mode (the same as runtime suspend) from the device suspend levels where
we lose control of HW and so must disable any HW access to dangling

get_crtc_from_states() is called before plane_state is copied to uapi,
so use the uapi state there.

intel_legacy_cursor_update() could probably get away with looking at
the hw state, but for clarity always look at the uapi state.

Changes since v1:
- Convert entirety of intel_legacy_cursor_update (Ville).

Prepare to split up hw and uapi machinally, by adding a uapi and
hw alias. We will remove the base in a bit. This is a split from the
original uapi/hw patch, which did it all in one go.

Now that we separated everything into uapi and hw, it's
time to make the split definitive. Remove the union and
make a copy of the hw state on modeset and fastset.

Color blobs are copied in crtc atomic_check(), right
before color management is checked.

Changes since v1:
- Copy all blobs immediately after drm_atomic_helper_check_modeset().
- Clear crtc_state->hw on disable, instead of using clear_intel_crtc_state().
Changes since v2:
- Use intel_crtc_free_hw_state + clear in intel_crtc_disable_noatomic().
- Make a intel_crtc_prepare_state() function that clears the crtc_state
  and copies hw members.
- Remove setting uapi.adjusted_mode, we now have a direct call to
  drm_calc_timestamping_constants().
Changes since v3:
- Rename prefix copy_hw_to_uapi_state() with intel_crtc.
- Copy color blobs to uapi as well.
- Add a intel_crtc_copy_uapi_to_hw_state_nomodeset() function for clarity.
Changes since v4:
- Copy hw.adjusted_mode back to uapi.adjusted_mode, to shut up
  the call to drm_calc_timestamping_constants() in
  drm_atomic_helper_update_legacy_modeset_state().
- Use drm_property_replace_blob (Ville).
Changes since v5:
- Use hw->mode in intel_modeset_readout_hw_state(). (Ville)
- Copy to uapi.mode using drm_atomic_set_mode_for_crtc(). (Ville)

Split up crtc_state->base to uapi. This is done using the following patch,
ran after the previous commit that splits out any hw references:

struct intel_crtc_state *T;

-T->base
+T->uapi
