Subject: [PATCH -next] kernel/power: Fix some kernel-doc comments

Add parameter description in alloc_rtree_node() kernel-doc
comment and fix several inconsistent function name descriptions.

Remove some warnings found by running scripts/kernel-doc,
which is caused by using 'make W=1'.

Applied as 5.19 with edits in the subject and some comment adjustments
to avoid line breaks in kerne-doc.

Thanks!
