[PATCH v3 17/24] drm/rockchip: dw-mipi-dsi: improve PLL configuration

The multiplication ratio for the PLL is required to be even due to the use of a "by 2 pre-scaler". Currently we are likely to end up with an odd multiplier even though there is an equivalent set of parameters with an even multiplier. For example, using the 324MHz bit rate with a reference clock o
