The TCNE2 bit of the DEFR6 register was renamed to TCNE1 in the R-Car gen2 manuals -- which makes more sense as that bit controls whether DU1, not DU2 is connected to TCON.
While at it, add the TCNE0 bit which controls whether DU0 is connected to TCON.
Based on the large patch by Andrey Gusakov andrey.gusakov@cogentembedded.com.
