Describe CMTs in the R8A779{7|8}0 device trees.

Based on the original (and large) patches by Vladimir Barinov.

This patch is against the 'renesas-devel-20180906-v4.19-rc2' branch of
Simon Horman's 'renesas.git' repo.

The R8A779{7|8}0 CMT DT binding updates have been posted the other day...

Changes in version 2:
- added the "resets" prop to all CMT nodes;
- credited Vladimir Barinov as the formal author of the original patches.

Thanks Sergei,

This looks fine to me but I will wait to see if there are other reviews
before applying.
