    WA_14020863754: Corner case with Min Hblank Fix can cause
    audio hang
    
    Issue: Previously a fix was made to avoid issues with extremely
    small hblanks, called the "Min Hblank Fix". However, this can
    potentially cause an audio hang.
    
    Workaround :
    During "Audio Programming Sequence" Audio Enabling -
    When DP mode is enabled Set mmio offset 0x65F1C bit 18 = 1b,
    before step #1 "Enable audio Presence Detect"
    
    During "Audio Programming Sequence" Audio Disabling -
    When DP mode is enabled Clear mmio offset 0x65F1C bit 18 = 0b,
    after step #6 "Disable Audio PD (Presence Detect)"
    If not clearing PD bit, must also not clear 0x65F1C bit 18 (leave = 1b)
    
    v2: Update the platform checks (Jani Nikula)
    
    v3: Limited the WA to LNL and BMG, added a helper (Matt Roper)
    
    v4: Updated the bit naming, fixed redundant if statement
