[edk2-devel] [Patch] OvmfPkg/QemuVideoDxe: Remove dependency on OptionRomPkg

[Michael D Kinney]

Update the QemuVideoDxe driver to not depend on the
OptionRomPkg to support moving OptionRomPkg to the
edk2-platforms repository.

The only dependency on the OptionRomPkg is the use of
PcdDriverSupportedEfiVersion to set the version value in the
EFI Driver Supported EFI Version Protocol.  This protocol is
intended for use in drivers for add-in devices, which does not
apply to the QEMU integrated video controller.  Since this
protocol does not apply to QEMU environment, remove both the
PCD and the installation of the EFI Driver Supported EFI
Version Protocol.
