6.8-rc4 psr delays boot by 2+ seconds

void intel_psr_init(struct intel_dp *intel_dp)
...
  if (!intel_dp_is_edp(intel_dp))
    intel_psr_init_dpcd(intel_dp);

New psr changes cause a boot delay since 6.8rc1. Commenting out the above lines in display/intel_psr.c reverts the delay and guc loads pretty much immediately after dmc like it does in 6.7. The message Panel replay is not supported by panel shows up in dmesg a few times after loading dmc firmware. Between dmc firmware loading and guc loading there is 2+ seconds of wait (sometimes this seems to vary). More drm:intel_dp_aux_xfer [i915]] AUX C/DDI C/PHY C: timeout (status 0x7d40023f) messages appear as well and go away with the psr_init_dpcd removed.
