Subject: [PATCH] drm/amd/display: avoid calling missing .resync_fifo_dccg_dio()

From: Arnd Bergmann <arnd@...db.de>

The .resync_fifo_dccg_dio() callback pointer was added in an #ifdef block,
but is called unconditionally:

drivers/gpu/drm/amd/amdgpu/../display/dc/dce110/dce110_hw_sequencer.c:2292:31: error: 'struct hwseq_private_funcs' has no member named 'resync_fifo_dccg_dio'

Add the same #ifdef around the caller as well.

Fixes: 6354b0dc3a7a ("drm/amd/display: Trigger DIO FIFO resync on commit streams")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
