Add a DRM_CLASSMAP_USE declaration to 2nd batch of helpers and *_drv.c
files. For drivers, add the decl just above the module's PARAMs,
since it identifies the "inherited" drm.debug param.
Note: with CONFIG_DRM_USE_DYNAMIC_DEBUG=y, a module not also declaring
DRM_CLASSMAP_USE will have its class'd prdbgs stuck in the initial
(disabled, but for DEBUG) state.
The stuck sites are evident in /proc/dynamic_debug/control as:
class:_UNKNOWN_ _id:N # control's last column
rather than a proper "enumeration":
class:DRM_UT_CORE
TLDR: This set of updates was found by choosing M for all DRM-config
items I found (not allmodconfig), building & modprobing them, and
grepping "class unknown," control. There may yet be others.
