6fd5a7c92e drm/i915/dp: Fix eDP max rate for display 11+
intel_dp_set_source_rates() calls intel_dp_is_edp(), which is unsafe to
use before intel_encoder->type is set. This causes incorrect max source
rate to be used for display 11+. On EHL and JSL, HBR3 is used instead of
HBR2, and on the other affected platforms, HBR2 is used instead of HBR3.

Move intel_dp_set_source_rates() to after intel_encoder->type is
set. Add comment to intel_dp_is_edp() describing unsafe usages. Cleanup
intel_dp_init_connector() while at it.

Note: The same change was originally added as commit 680c45c767
("drm/i915/dp: Correctly advertise HBR3 for GEN11+"), but later reverted
due to issues in CI in commit d391301960 ("Revert "drm/i915/dp:
Correctly advertise HBR3 for GEN11+"").

Pull drm updates from Dave Airlie:
 "Highlights:

   - i915 has seen a lot of refactoring and uAPI cleanups due to a
     change in the upstream direction going forward

     This has all been audited with known userspace, but there may be
     some pitfalls that were missed.

   - i915 now uses common TTM to enable discrete memory on DG1/2 GPUs

   - i915 enables Jasper and Elkhart Lake by default and has preliminary
     XeHP/DG2 support

   - amdgpu adds support for Cyan Skillfish

   - lots of implicit fencing rules documented and fixed up in drivers

   - msm now uses the core scheduler

   - the irq midlayer has been removed for non-legacy drivers

   - the sysfb code now works on more than x86.

  Otherwise the usual smattering of stuff everywhere, panels, bridges,
  refactorings.

  Detailed summary:
