Without this header, the use of FIELD_PREP() can cause a build failure:
drivers/gpu/drm/meson/meson_venc.c: In function 'meson_encl_set_gamma_table':
drivers/gpu/drm/meson/meson_venc.c:1595:24: error: implicit declaration of function 'FIELD_PREP' [-Werror=implicit-function-declaration]
Fixes: 51fc01a03442c ("drm/meson: venc: add ENCL encoder setup for MIPI-DSI output")
