drm/amd/display: dpia should avoid encoder used by dp2
[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.
