drm/i915/psr: Disable PSR on update_m_n and update_lrr
PSR/PR parameters might change based on update_m_n or update_lrr. Disable
on update_m_n and update_lrr to ensure proper parameters are taken into use
on next PSR enable in intel_psr_post_plane_update.
Closes: https://gitlab.freedesktop.org/drm/i915/kernel/-/issues/15771
Fixes: 2bc98c6f97af ("drm/i915/alpm: Compute ALPM parameters into crtc_state->alpm_state")
Cc: <stable@vger.kernel.org> # v6.19+
