[PATCH] drm/rockchip: vop2: add missing bitfield.h include

[Heiko Stuebner]

Commit 328e6885996c ("drm/rockchip: vop2: Add platform specific callback")
moved per soc configuration code to the other per-soc data into
rockchip_vop2_reg.c, but forgot to also include bitfield.h for the used
FIELD_PREP macro. Add this missing include.
