phy: rockchip: samsung-hdptx: Reduce ROPLL loop bandwidth
Due to its relatively low frequency, a noise stemming from the 24MHz PLL
reference clock may traverse the low-pass loop filter of ROPLL, which
could potentially generate some HDMI flash artifacts.
Reduce ROPLL loop bandwidth in an attempt to mitigate the problem.
