Include <linux/of.h> in drm_modes.c for of_property_read_u32(). Until now, the OF header got included via <linux/fb.h>. Also comment on the reason for still including <linux/fb.h>. The header file is still required to get KHZ2PICOS(). The macro is part of the UAPI headers, so it cannot be moved to a less prominent location.
