882ecff709 drm/i915: Use intel_crtc_needs_modeset() more 
Prefer our own intel_crtc_needs_modeset() wrapper to
drm_atomic_crtc_needs_modeset() whenever we are dealing
with the intel_ types instead of drm_ types. Makes things
a bit neater in general.

334810f820 drm/i915: Fix watermark calculations for DG2 CCS+CC modifier 
Take the DG2 CCS+CC modifier into account when calculating the
watermarks. Othwerwise we'll calculate the watermarks thinking this
tile-4 modifier is linear.

62a21a7c6a drm/i915/ipc: register debugfs only if IPC available 
It looks like trying to enable IPC via debugfs on platforms that don't
have IPC resulted in dmesg info message about IPC being enabled, which
is clearly not possible and would not happen.

Seems sensible to register IPC debugfs only on platforms that have IPC.
