Drop unused macros from the rcar_canfd.c.
Reported-by: Vincent Mailhol <mailhol.vincent@...adoo.fr>
Closes: https://lore.kernel.org/all/7ff93ff9-f578-4be2-bdc6-5b09eab64fe6@wanadoo.fr/

v2->v3:
* Added Rb tag from Geert and Vincent.
v1->v2:
* Dropped the Rb tags.
* Restored simple bit definitions as it serve as documentation.
* Restored register offsets, as it will become anonymous gaps when the
register offsets are replaced by C structs.
