    drm/amd/display: Apply w/a for hard hang on HPD

    [Why]
    HPD disable and enable sequences are not mutually exclusive
    on Linux. For HPDs that spans under 1s (i.e. HPD low = 1s),
    part of the disable sequence (specifically, a request to SMU
    to lower refclk) could come right before the call to PHY
    enablement, causing DMUB to access an irresponsive PHY
    and thus a hard hang on the system.

    [How]
    Disable 48mhz refclk off when there is any HPD status in
    connected state.
