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.

spi: dt-bindings: Fix unevaluatedProperties warnings in examples

The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples.

'spi-max-frequency' is supposed to be a per SPI peripheral device property,
not a SPI controller property, so drop it.
