Change in coreboot[master]: soc/mediatek: dsi: Refactor MIPI TX configuration

[Hung-Te Lin (Code Review)]

Hello Yu-Ping Wu, yongqiang niu, Julius Werner, You-Cheng Syu, jitao shi,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#2).

Change subject: soc/mediatek: dsi: Refactor MIPI TX configuration

soc/mediatek: dsi: Refactor MIPI TX configuration

The only platform-specific difference in mtk_dsi_phy_clk_setting is how
to configure MIPI TX because those registers (and logic) are quite
different across different SOCs.

The calculation of data rate is actually the same so we should isolate
it and move to common, and rename mtk_dsi_phy_clk_setting to a better
name as mtk_dsi_configure_mipi_tx.

BUG=b:80501386,b:117254947
TEST=make -j # board = oak and boots
