edid: use physical dimensions if available
Replace dpi with width_mm/height_mm in qemu_edid_info. Use it when set (non-zero) to compute the DPI and generate the EDID. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-id: 20200927145751.365446-3-marcandre.lureau@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
