b5f1135ba8 gpu: nvgpu: utils: improve CCM for rbtree
This improves the code complexity of the rbtree function
nvgpu_rbtree_unlink() by creating helper functions swap_in_new_child()
and adopt_children().

This reduces the TCC metric to 9.

5e0bf2bb7a gpu: nvgpu: utils: improve CCM for rbtree
Improve the code complexity for the rbtree function delete_fixup().
Create smaller functions, delete_fixup_right_child() and
delete_left_child() to handle those parts of the agorithm. Also, create
helper function has_no_red_children() to handle a common check in these
new functions.

This brings the TCC metric to 7.

09f7dd7fdd gpu: nvgpu: utils: fix CERT-C violations
Rule INT31-C requires that integer conversions do not result in lost or
misinterpreted data.
Rule INT32-C requires that operations on signed integers do not result
in overflow.
Rule EXP34-C requires that pointer dereferences never include NULL.
Fix violations of these types in nvgpu.common.utils.

9e3f0b22e9 gpu: nvgpu: Move code to utils unit
The utils unit contains utilities that are useful to everyone. Things
like rbtree, enabled, string, etc go here. This helps prevent clutter
in the top level common directory. Also by organizing source code into
these top level units we reduce our SWUD burden: all utility code may
be described by one SWUD instead of many tiny SWUDs.
