The vPHB model of the cxl kernel API is a hierarchy where the AFU is represented by the vPHB, and it's AFU configuration records are exposed as functions under that vPHB. If there are no AFU configuration records we will create a vPHB with nothing under it, which is a waste of resources and will opt us into EEH handling despite not having anything special to handle. This also does not make sense for cards using the peer model of the cxl kernel API, where the other functions of the device are exposed via additional peer physical functions rather than AFU configuration records. This model will also not work with the existing EEH handling in the cxl driver, as that is designed around the vPHB model. Skip creating the vPHB for AFUs without any AFU configuration records, and opt out of EEH handling for them.
