PM: runtime: Documentation: add runtime_status ABI document

Browse Source 
/sys/devices/.../power/runtime_status is introduced by commit c92445fadb
("PM / Runtime: Add sysfs debug files").  Then commit 0fcb4eef82 ("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.
