drm/amd/display: Consolidate HPO enable/disable and restrict only to state transitions.
[WHY]
Previously, we'd disabled HPO whenever an HPO display was disconnected. This
caused other HPO displays to blank whenever one was unplugged.
[HOW]
This change restricts HPO enable/disable to dce110_apply_ctx_to_hw and adds a
helper function (dce110_is_hpo_enabled) that returns true if any HPO displays
are present in a context. We compare the current and previous dc ctx to check
whether HPO is transitioning from on to off or vice versa, and adjust the HPO
state accordingly.
