PM: runtime: Documentation: add runtime_status ABI document
/sys/devices/.../power/runtime_status is introduced by commit c92445fadb91 ("PM / Runtime: Add sysfs debug files"). Then commit 0fcb4eef8294 ("PM / Runtime: Make runtime_status attribute not debug-only (v. 2)") made the runtime_status attribute available without CONFIG_PM_ADVANCED_DEBUG. This adds missing runtime_status ABI document. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

+Description:
+ The /sys/devices/.../power/runtime_status attribute contains
+ the current runtime PM status of the device, which may be
+ "suspended", "suspending", "resuming", "active", "error" (fatal
+ error), or "unsupported" (runtime PM is disabled).
