PM / Domains: Move syscore flag from subsys data to struct device
The syscore device PM flag is used to mark the devices (belonging to a PM domain) that should never be turned off, except for the system core (syscore) suspend/hibernation and resume stages. That flag is stored in the device's struct pm_subsys_data object whose address is available from struct device. However, in some situations it may be convenient to set that flag before the device is added to a PM domain, so it is better to move it directly to the "power" member of struct device. Then, it can be checked by the routines in drivers/base/power/runtime.c and drivers/base/power/main.c, which is more straightforward. This also reduces the number of dev_gpd_data() invocations in the generic PM domains framework, so the overhead related to the syscore flag is slightly smaller. Signed-off-by: Rafael J.
