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.
