The runtime PM platform support stub in use by ARM-based SH/R-Mobile platforms contains nothing that's specifically ARM-related and instead of wholly generic to anything using the clock framework. The recent runtime PM changes interact rather badly with the lazy disabling of clocks late in the boot process through the clock framework, leading to situations where the runtime suspend/resume paths are entered without a clock being actively driven due to having been lazily gated off. In order to correct this we can trivially tie in the aforementioned stub as a general fallback for all SH platforms that don't presently have their own runtime PM implementations (the corner case being SH-based SH-Mobile platforms, which have their own stub through the hwblk API -- which in turn has bitrotted and will be subsequently adapted to use the same stub as everyone else), regardless of whether the platforms choose to define power domains of their own or not. This fixes up regressions for clock framework users who also build in runtime PM support without any specific power domains of their own, which was previously causing the serial console to be lost when warring with lazy clock disabling.
