    drm/mediatek: dp: Add phy_mtk_dp module as pre-dependency
    
    [ Upstream commit c8048dd0b07df68724805254b9e994d99e9a7af4 ]
    
    The mtk_dp driver registers a phy device which is handled by the
    phy_mtk_dp driver and assumes that the phy probe will complete
    synchronously, proceeding to make use of functionality exposed by that
    driver right away. This assumption however is false when the phy driver
    is built as a module, causing the mtk_dp driver to fail probe in this
    case.
    
    Add the phy_mtk_dp module as a pre-dependency to the mtk_dp module to
    ensure the phy module has been loaded before the dp, so that the phy
    probe happens synchrounously and the mtk_dp driver can probe
    successfully even with the phy driver built as a module.
