mtd: rawnand: omap_elm: convert DT binding to yaml

Hi,

This series converts omap_elm DT bindings to yaml and adds support for ELM on AM64 SoC.

Changelog:
v3
- use 'enum' for compatible specifier. Get rid of 'items'.

v2
- explain hwmod usage deprecated in commit log
- fix example node name to 'ecc'
- remove 'items' for single compatible specifier

cheers,
-roger

Convert elm.txt to ti,elm.yaml.

hwmod framework use is deprecated for new platforms so mark it so.

TI's AM64 SoC has the Error Locator Module. Add compatible and related properties to support ELM on AM64 SoC.

The AM64 SoC has the Error Locator Module. Add compatible id for it.
