From: Peichen Huang <[email protected]> [WHY] In current HPO DP2 implementation, driver would enable/disable DIG encoder when configuring HPO DP2. Therefore, usb4 dp tunnelling should not use the DIG encoder if the corresponded phy is used by a HPO DP2 stream.
[HOW] A DP2 stream is treated as a dig stream.
