drm_print: add _ddebug descriptor to drm_*dbg prototypes
upgrade the callchain to drm_dbg() and drm_dev_dbg(); add a struct
_ddebug ptr parameter to them, and supply that additional param by
replacing the '_no_desc' flavor of dyndbg Factory macro currently used
with the flavor that supplies the descriptor.
NOTES:
The descriptor gives these fns access to the decorator flags, but they
do none of the dynamic-prefixing done by dynamic_emit_prefix(), which
is currently static.
DRM already has conventions for logging/messaging; just tossing
optional decorations on top probably wouldn't help. Instead, existing
flags (or new ones, perhaps 'sd' ala lspci) can be used to make
current message conventions optional. This suggests a new
drmdbg_prefix_emit() to handle prefixing locally.
For CONFIG_DRM_USE_DYNAMIC_DEBUG=N, just pass null descriptor.
desc->class_id is redundant with category parameter, but its
availability is dependent on desc.
