R-Car M3-W needs a delay of 1 µs before powering off the A3IR and A3VC
power domains. Add support for this using a new flag, which indicates
that a power area is subject to this quirk.
Inspired by a patch in the BSP by Dien Pham.

It has been pointed out that naming a subsystem "genpd" isn't very
self-explanatory and the acronym itself that means Generic PM Domain, is
known only by a limited group of people.
In a way to improve the situation, let's rename the subsystem to pmdomain,
which ideally should indicate that this is about so called Power Domains or
"PM domains" as we often also use within the Linux Kernel terminology.
