drm/amd/display: Refactor HDCP encryption status update
[Why]
The old way was to poll PSP and update the properties. But due to a
limitation in the PSP interface this doesn't work for MST.
[How]
According to PSP if set_encryption return success, the link is encrypted
and the only way it will not be is if we get a link loss(which we handle
already).
So this method should be good enough to report HDCP status.
