[Impact]

DP tunneling on a certain thunderbolt docking doesn't work well.

[Fix]

Add a new IP version in the switch cases that supports DPIA.

[Test Case]

Connect an external monitor via thunderbolt docking station.

[Where problems could occur]

DPIA is supported on AMD DCN314 gpu platforms. With or without it may
both introduce compatibility issues as what to be solve here.

[Other Info]

While this applies to AMD Phoenix/Phoenix2 platforms, only oem-6.0 or
above are nominated for fix.
