Hi Simon, Magnus,
Now CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS are enabled unconditionally
for Renesas ARM-based SoCs, the legacy clock domain is no longer used on
these SoCs, and we can return drivers/sh/ to SuperH.
Both patches were extracted from series "[PATCH 0/4] Enable PM and
PM_GENERIC_DOMAINS for SoCs with PM Domains", and updated, hence the
v2.
Note that this does break booting R-Car Gen2 boards using pre-v4.3 DTSes
that don't have power-domains properties, as this relied on the legacy
clock domain.
Thanks!

Since commits 71d076ceb245f0d9 ("ARM: shmobile: Enable PM and
PM_GENERIC_DOMAINS for SoCs with PM Domains") and 2ee98234b88174f2
("arm64: renesas: Enable PM and PM_GENERIC_DOMAINS for SoCs with PM
Domains"), CONFIG_PM and CONFIG_PM_GENERIC_DOMAINS are enabled
unconditionally for Renesas ARM-based SoCs. Hence the legacy clock
domain is no longer used on these SoCs.
Remove the related support code, and stop entering drivers/sh/ on ARM.

Thanks, I have queued this up for v4.8 which should give it a good
amount of time to sit in next.
