	Hi Simon, Magnus,

When DT SYSC support was introduced in v4.7, legacy fallbacks were kept
to keep secondary CPUs working on R-Car H1, H2, and M2-W using old DTBs.
However, the time has come to drop these fallbacks, and clean up the
resulting code.

Most of this was written when I worked on DT SYSC support, but postponed
until the time was ripe.  So basically I've been running this during the
last +2 years.

I avoided touching drivers/soc/renesas and arch/arm/mach-shmobile code
in the same patch.  If you prefer some patches to be squashed, please
let me know.

Tested on Marzen (R-Car H1), Lager (R-Car H2), and Koelsch (R-Car M2-W).

Thanks!

when I'm talking to journalists I just say "programmer" or something like that.
