OvmfPkg: remove gEfiLegacy8259ProtocolGuid
At this point, gEfiLegacy8259ProtocolGuid is unused; remove it. This shrinks the list of resources scheduled for removal to: - PCDs: - Pcd8259LegacyModeEdgeLevel - Pcd8259LegacyModeMask Cc: Ard Biesheuvel <ardb+tianocore@kernel.org> Cc: Gerd Hoffmann <kraxel@redhat.com> Cc: Jiewen Yao <jiewen.yao@intel.com> Ref: https://bugzilla.tianocore.org/show_bug.cgi?id=4588 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Message-Id: <20231110235820.644381-36-lersek@redhat.com> Reviewed-by: Jiewen Yao <Jiewen.yao@intel.com> Reviewed-by: Ard Biesheuvel <ardb@kernel.org> Acked-by: Corvin Köhne <corvink@FreeBSD.org> Acked-by: Gerd Hoffmann <kraxel@redhat.com>
