[PATCH AUTOSEL 5.2 23/59] drm/bridge: tc358764: Fix build error

[Sasha Levin]

From: YueHaibing <yuehaibing@xxxxxxxxxx>

[ Upstream commit e1ae72a21e5f0d1846e26e3f5963930664702071 ]

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.
