OvmfPkg: exclude the CSM-based VideoDxe driver
The CSM-based VideoDxe driver is a special UEFI_DRIVER module that both follows and doesn't follow the UEFI driver model. Namely, in the Supported and Start members of its Driver Binding Protocol instance, it consumes the Legacy Bios Protocol directly from the UEFI protocol database, as opposed to (only) opening protocols on the handle that it is supposed to bind. Furthermore, the driver "marks" its own image handle with the NULL-interface "Legacy Bios" (pseudo-protocol) GUID, in order to "inform back" the provider of the Legacy Bios Protocol, i.e., LegacyBiosDxe, that VideoDxe is a "BIOS Thunk Driver" in the system. Quoting "OvmfPkg/Csm/Include/Guid/LegacyBios.h", such a driver follows the UEFI Driver Model, but still uses the Int86() or FarCall() services of the Legacy Bios Protocol as the basis for the UEFI protocol it produces. In a sense, there is a circular dependency between VideoDxe and LegacyBiosDxe; each knows about the other. However, VideoDxe is a UEFI_DRIVER, while LegacyBiosDxe is a platform DXE_DRIVER with a very long DEPEX. Therefore, for keeping dependencies conceptually intact, first exclude VideoDxe from the OVMF platforms. Always include the hypervisor-specific real UEFI video driver. --*-- Note that the pathname "IntelFrameworkModulePkg/Csm/BiosThunk/VideoDxe/VideoDxe.inf" in the bhyve platform DSC and FDF files is bogus anyway.
