OK good news and bad news.

* The good news: this means the patch "works" and you're now seeing the extra
values for power slider notifications.

* The bad news: It appears that HP's EC doesn't do "all" the power state change
notifications.  Some of it is handled by code that runs in the APU's TEE
environment.

> [45870.908318] amd-pmf AMDI0102:00: supported functions:0xe0c3
> notifications:0x10

There are some other bits not yet supported by amd-pmf in Linux.  Let's leave
this issue opened until that code is submitted.
