clk: renesas: cpg-mssr: Keep wakeup sources active during system suspend
If a device is part of the CPG/MSSR Clock Domain and to be used as a
wakeup source, it must be kept active during system suspend.
Currently this is handled in device-specific drivers by explicitly
increasing the use count of the module clock when the device is
configured as a wakeup source. However, the proper way to prevent the
device from being stopped is to inform this requirement to the genpd
core, by setting the GENPD_FLAG_ACTIVE_WAKEUP flag.
Note that this will only affect devices configured as wakeup sources.
