Subject: [PATCH] drm/mediatek: Support MT8195 OVL compatible in mtk_drm_drv

Specify the component type for mediatek,mt8195-disp-ovl in the MediaTek
DRM driver on top of commit 76cdcb87d391 ("drm/mediatek: Add MT8195 ovl
driver support").

With this, the compatible can function as an independent fallback for
other display overlays without relying on MT8192.
