If CONFIG_DRM_TOSHIBA_TC358764=y but CONFIG_DRM_KMS_HELPER=m,
building fails:
drivers/gpu/drm/bridge/tc358764.o:(.rodata+0x228): undefined reference to
`drm_atomic_helper_connector_reset'
drivers/gpu/drm/bridge/tc358764.o:(.rodata+0x240): undefined reference to
`drm_helper_probe_single_connector_modes'
drivers/gpu/drm/bridge/tc358764.o:(.rodata+0x268): undefined reference to
`drm_atomic_helper_connector_duplicate_state'
drivers/gpu/drm/bridge/tc358764.o:(.rodata+0x270): undefined reference to
`drm_atomic_helper_connector_destroy_state'
Like TC358767, select DRM_KMS_HELPER to fix this, and
change to select DRM_PANEL to avoid recursive dependency.
