It's has been reported that some Samsung platforms fails to boot with
genpd's new sync_state support.
Typically the problem exists for platforms where bootloaders are turning on
the splash-screen and handing it over to be managed by the kernel. However,
at this point, it's not clear how to correctly solve the problem.
Although, to make the platforms boot again, let's add a temporary hack in
the samsung power-domain provider driver, which enforces a sync_state that
allows the power-domains to be reset before consumer devices starts to be
attached.

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.
