with DRM_USE_DYNAMIC_DEBUG=y now un-BROKEN
for configs like:
CONFIG_DRM_USE_DYNAMIC_DEBUG=y
# CONFIG_DYNAMIC_DEBUG is not set
CONFIG_DYNAMIC_DEBUG_CORE=y
this module gets macro breakage:

These sources include drm_print.h, which includes dynamic_debug.h and
then checks DRM_USE_DYNAMIC_DEBUG, to decide if drm_dbg() rides on
dynamic-debug underneath.
DRM_USE_DYNAMIC_DEBUG is possible with DYNAMIC_DEBUG_CORE alone, but
dynamic_debug.h also requires DYNAMIC_DEBUG_MODULE before defining
those macros above.
drm/Makefile adds this to cflags on behalf of all drivers, do so for
this driver. TBC: do subdir-cflags in drivers/accel/Makefile instead,
for all accel/* modules.
RFC: Maybe decouple from DRM, at least the DRM_USE_DYNAMIC_DEBUG
itself (ie just CONFIG_DYNAMIC_DEBUG_CORE). Its not obvious that
XDNA_DBG should be categorized with DRM_UT_DRIVER by default.
Do we need a new DRM_UT_ACCEL category ?
