drm/bridge: tc358768: select CONFIG_VIDEOMODE_HELPERS
[ Upstream commit 26513300978f7285c3e776c144f27ef71be61f57 ]
A dependency on this feature was recently introduced:
x86_64-linux-ld: vmlinux.o: in function `tc358768_bridge_pre_enable':
tc358768.c:(.text+0xbe3dae): undefined reference to `drm_display_mode_to_videomode'
Make sure this is always enabled.
