The DSI 10nm PLL driver was apparently ported from downstream, but some of its "features" were not ported over, for a good reason. Pity is that the removal of the downstream dependencies broke the clock calculation logic for this driver and that made it impossible to use any DSI display on at least MSM8998.
This patch series fixes the calculation issues and also solves some TODOs that I've found in this driver.
Tested on: - Sony Xperia XZ Premium (MSM8998) dual-dsi command-mode LCD display - F(x)Tec Pro1 (MSM8998) single dsi, video-mode OLED display
