Add OVL compatible name for MT8195.
Reviewed-by: CK Hu <ck.hu@xxxxxxxxxxxx>
but it's weird to put this patch into IGT series. Without this patch,
mt8195 drm driver does not work not only IGT.
The driver does work because the devicetree node declares two compatibles,
"mediatek,mt8195-disp-ovl", "mediatek,mt8183-disp-ovl" where the second
compatible is matched in mtk_drm_drv, and the first is matched in mtk_disp_ovl
as both are platform_driver.
This commit is not necessary, even... :-)
