Linux uses ECDT only in boot stage (before the namespace is fully initialized), but there are cases reported that Windows allows ECDT to be used for OSPM runtime, responding EC events by evaluating _Qxx methods under the device node indicated in the ECDT.
This patchset changes Linux ECDT support to follow Windows behavior and also fixes related boot_ec support. v2: Rebased on top of recent linux-pm.git/linux-next. Addressed 1 comment from Peter Wu. Update patch SOBs.
