Especially it's actual for the recent AM65x/J721E/J7200 SoC and feature AM64x, which supports features like: auto-aging, classifiers, Link aggregation, additional hw filtering, etc. Existing ALE configuration interface is not practical in terms of adding new features and requires consumers to program a lot static parameters. Any attempt to add new options will case endless adding and maintaining different combination of flags and options. Hence CPSW ALE configuration is static and fixed for SoC (or set of SoC) It is reasonable to add support for static ALE configurations inside ALE module. This patch adds static ALE configuration table for different ALE versions and provides option for consumers to select required ALE configuration by providing ALE const char *dev_id identifier. This feature is not enabled by default until existing CPSW drivers will be modified by follow up patches.

So, handling them using flags, defines and get/set functions became over-complicated. This patch introduces tables to describe the ALE VLAN entries fields, which are different between TI CPSW ALE versions, and new get/set access functions. It also allows to detect incorrect access to not available ALL entry fields.
