[PATCH] Fix drm documentation warning

[Taichi Nishimura]

Sorry to re-send this patch again.
I forgot to attach description.

When running make htmldocs, I found that drm_accel_node
does not exist. The documents do not have any links to
acceleration nodes, so I removed them.

This patch is an extra credit for documentation task
in the Linux kernel Bug Fixing Spring unpaid 2023.

Best,
Taichi
