drm/i915/psr: Add PSR pause/resume reference count
We have now seen this:
<4> [2120.434153] i915 0000:00:02.0: [drm] drm_WARN_ON(psr->paused)
<4> [2120.434196] WARNING: CPU: 3 PID: 4430 at drivers/gpu/drm/i915/display/intel_psr.c:2227 intel_psr_pause+0x16e/0x180 [i915]
Comment for drm_WARN_ON(display->drm, psr->paused) in intel_psr_pause says:
"If we ever hit this, we will need to add refcount to pause/resume"
This patch is implementing PSR pause/resume refcount.
v3: Incorporate changes missing from v2
v2: Add drm_warn for detecting possible unbalanced pause/resume
