PM / Runtime: Add sysfs debug files
Add a few sysfs files relating to runtime power management for
advanced debug purposes:
runtime_enabled: is runtime PM enabled for this device? States
are "enabled", "disabled", "forbidden" or a combination
of the latter two.
runtime_status: what state is the device in currently? E.g., it
reports "suspended" for runtime-suspended devices, and
"active" for active devices. NOTE: if runtime_enabled
returns "disabled", the value of this file may not
reflect its physical state.
runtime_usage: the runtime PM usage count of a device
runtime_active_kids: the runtime PM children usage count of a device, or
0 if the ignore_children flag is set.
Also, CONFIG_PM_SLEEP_ADVANCED_DEBUG is not defined in any Kconfig
file, so replace it with CONFIG_PM_ADVANCED_DEBUG.
