    drm/i915/dp: Guarantee a minimum HBlank time
    
    Mandate a minimum Hblank symbol cycle count between BlankingStart and
    BlankingEnd in 8b/10b MST and 128b/132b mode.
    
    v2: Affine calculation/updation of min HBlank to dp_mst (Jani)
    v3: moved min_hblank from struct intel_dp to intel_crtc_state (Jani)
    v4: use max/min functions, change intel_xx *intel_xx to intel_xx *xx
        (Jani)
        Limit hblank to 511 and accommodate BS/BE in calculated value
        (Srikanth)
    v5: Some spelling corrections (Suraj)
    v6: Removed DP2.1 in comment as this is applicable for both DP2.1 and
        DP1.4 (Suraj)
    v7: crtc_state holds the logical values and the register value
        computation is moved to mst_enable() (Jani)
    v8: Limit max hblank to 0x10, disable min_hblank on mst_disable (Jani)
