Caesar Wang e085a8a359 rockchip/rk3399: enable DPLL SSC for DDR EMI test on bob
Spread Spectrum Modulator (SSMOD) is a fully-digital circuit used to
modulate the frequency of the Silicon Creations’ Fractional PLL in order
to reduce EMI.

We need to turn the DPLL spread spectrum feature on to
reduce the EMI noise for DDR on bob.
