HPD event may not be ready when configuring TCSS mux for DP,
check if any DP device is connected and wait for HPD ready before
TCSS configuration. Remove unnecessary dependency on mainboard
functions, use generic interface which provides USB-C mux
operations.
BUG=b:192947843
TEST=select ENABLE_TCSS_DISPLAY_DETECTION in Kconfig.name for
Brya. Build coreboot and update your Brya. Boot Brya with USB-C
display connected, you should find `HPD ready after %lu ms` and
`Port C%zd is configured to DP mode!` in coreboot log. Display
should show screen in developer mode or recovery mode.
