[PATCH 1/3] PM: domains: Add GENPD_FLAG_RPM_ALWAYS_ON for the always-on governor

[Ulf Hansson]

Rather than relying on the genpd provider to set the corresponding flag,
GENPD_FLAG_RPM_ALWAYS_ON, when the always-on governor is being used, let's
add it in pm_genpd_init(). In this way, it starts to benefits all genpd
providers immediately.
