This patch set addresses all the concerns raised at [1] to make the EM YNL spec
clearer. It includes the following changes:

- Fix the lint errors (1/4). 
- Rename em.yaml to dev-energymodel.yaml (2/4).  “dev-energymodel” was used
  instead of “device-energy-model”, which was originally proposed [2], because
  the netlink protocol name cannot exceed GENL_NAMSIZ(16). In addition, docs
  strings and flags attributes were added.
- Change cpus' type from string to u64 array of CPU ids (3/4).
- Add dump to get-perf-domains in the EM YNL spec (4/4). A user can fetch
  either information about a specific performance domain with do or information
  about all performance domains with dump. 

ChangeLog v1 -> v2:
- Remove perf-domains in the YNL spec, as do and dump of get-perf-domains
  share the reply format using perf-domain-attrs (4/4).
- Add example outputs of get-perf-domains and get-perf-table for ease of
  understanding (cover letter).
v2 looks good, thanks!
