    drm/v3d: Add support for V3D v4.2. · eea9b97b

    No compatible string for it yet, just the version-dependent changes.
    They've now tied the hub and the core interrupt lines into a single
    interrupt line coming out of the block.  It also turns out I made a
    mistake in modeling the V3D v3.3 and v4.1 bridge as a part of V3D
    itself -- the bridge is going away in favor of an external reset
    controller in a larger HW module.
    
    v2: Use consistent checks for whether we're on 4.2, and fix a leak in
        an error path.
    v3: Use more general means of determining if the current 4.2 changes
        are in place, as apparently other platforms may switch back (noted
        by Dave).  Update the binding doc.
    v4: Improve error handling for IRQ init.
