drm/i915/psr: Apply underrun on PSR idle workaround
This patch is applying workaround for underrun on idle PSR HW issue
(Wa_16025596647) when PSR is getting enabled. It uses vblank enable/disable
status, DC5/6 enabled disabled and enabled pipes count information made
available.
This patch is also adding calls to dc5/dc6, vblank enable/disable and pipe
enable/disable notification functions as needed.
intel_psr_needs_block_dc_vblank is modified to get vblank enable/disable
notification on PSR capable system.
v2: use intel_dmc interface instead of directly writing dmc register
