    arm64: dts: renesas: r8a779g0: Add missing SCIF_CLK2
    
    [ Upstream commit 08e799f6bce80dd63c174d8d0fc61d1a6149960b ]
    
    R-Car V4H actually has two SCIF_CLK pins.
    The second pin provides the SCIF_CLK signal for HSCIF2 and SCIF4.
    
    Fixes: a4c31c56d2d35641 ("arm64: dts: renesas: r8a779g0: Add SCIF nodes")
    Fixes: 39d9dfc6fbe1860e ("arm64: dts: renesas: r8a779g0: Add remaining HSCIF nodes")
