tools: ynl: fix enum-as-flags in the generic CLI

Browse Source 
Lorenzo points out that the generic CLI is broken for the netdev
family. When I added the support for documentation of enums
(and sparse enums) the client script was not updated.
It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).
