[Intel-gfx] [PATCH v4 4/4] drm/i915/psr: Move intel_psr_disable_source() code to intel_psr_disable_locked()

[José Roberto de Souza]

In the past we had hooks to configure HW for VLV/CHV too, in the drop
of VLV/CHV support the intel_psr_disable_source() code was not moved
to the caller, so doing it here.
