drm/mm: Mark drm_mm_interval_tree*() functions with __maybe_unused
The INTERVAL_TREE_DEFINE() uncoditionally provides a bunch of helper
functions which in some cases may be not used. This, in particular,
prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y:
.../drm/drm_mm.c:152:1: error: unused function 'drm_mm_interval_tree_insert' [-Werror,-Wunused-function]
152 | INTERVAL_TREE_DEFINE(struct drm_mm_node, rb,
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
153 | u64, __subtree_last,
| ~~~~~~~~~~~~~~~~~~~~
154 | START, LAST, static inline, drm_mm_interval_tree)
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Fix this by marking drm_mm_interval_tree*() functions with __maybe_unused.
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
Fixes: 202b52b7fbf7 ("drm: Track drm_mm nodes with an interval tree")
