PM / Domains: Provide an always on power domain governor
Since systems are likely to have power domains that can't be turned off for various reasons at least temporarily while implementing power domain support provide a default governor which will always refuse to power off the domain, saving platforms having to implement their own. Since the code is so tiny don't bother with a Kconfig symbol for it. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
