Convert the mtk-btcvsd-snd.txt DT binding to DT Schema format.

Changes in v3:
Sorry about the spam. A second round of dt_binding_check + dtbs_check
led me to additional improvements:

- Use reg-names in place of a non-informative description property
- Simplify the reg property in the example

Changes in v2 [2]:
- Fixed issues from make dt_binding_check
- Set myself as maintainer for the binding

Initial version [1].
