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.
