dt-bindings: yamllint: Require a space after a comment '#'

Enable yamllint to check the preferred commenting style of requiring a
space after a comment character '#'. Fix the cases in the tree which
have a warning with this enabled. Most cases just need a space after the
'#'. A couple of cases with comments which were not intended to be
comments are revealed. Those were in ti,sa2ul.yaml, ti,cal.yaml, and
brcm,bcmgenet.yaml.
