[Hung-Te Lin (Code Review)]

Hello Yu-Ping Wu, yongqiang niu, Julius Werner, You-Cheng Syu, jitao shi, build bot (Jenkins),

soc/mediatek: dsi: Refactor PHY timing calculation

The PHY timing should be calculated by data rate (Mbps). However for 8173
some values were hard-coded so we want to introduce a mtk_phy_timing
structure and a weak function mtk_dsi_override_phy_timing that allows
per-SOC customization to fine tune PHY timings.

TEST=make -j # board = oak and boots
