drm/amd/display: Ignore k1/k2 values for virtual signal

[Why and How]
We are hitting k1/k2 assert when we are using a virtual signal in the
test; as a result, we are failing some automated tests with a false
positive. This commit addresses this issue by ignoring the assert
condition if we use SIGNAL_TYPE_VIRTUAL.
