[PATCH v2 2/4] can: m_can: clean up CCCR reg defs, order by revs

[Torin Cooper-Bennun <torin@maxiluxsystems.com>]

Ensures that the different CCCR regmasks for m_can revs 3.0.x, 3.1.x,
3.2.x and 3.3.x are clearly distinguishable. Removes incorrect
CCCR_CANFD define. Adds bit fields UTSU and WMM for rev 3.3.x, for
completeness.
