Add a generic netlink spec in YAML format and autogenerate boilerplate
code using ynl-regen.sh to introduce a generic netlink for the energy
model. It allows a userspace program to read the performance domain and
its energy model. It notifies the userspace program when a performance
domain is created or deleted or its energy model is updated through a
multicast interface.
Specifically, it supports two commands:
- EM_CMD_GET_PDS: Get the list of information for all performance
domains.
- EM_CMD_GET_PD_TABLE: Get the energy model table of a performance
domain.
Also, it supports three notification events:
- EM_CMD_PD_CREATED: When a performance domain is created.
- EM_CMD_PD_DELETED: When a performance domain is deleted.
- EM_CMD_PD_UPDATED: When the energy model table of a performance domain
is updated.
Finally, update MAINTAINERS to include new files.
