[PATCH v2] ASoC: dt-bindings: ssm2602: convert to dt schema

[Xiaxi Shen]

Convert adi,ssm2602 binding to DT schema

The original adi,ssm2602.txt contains bindings for 3 devices
SSM2602, SSM2603 and SSM2604. Since they share something
in common. So I created one single yaml and name it 260x instead.
Let me know if you think it should be done in another way.

It passed dt_binding_check and dtbs_check.

Changes in v2:
 - Change '2602' to '260x' in the variable $id and
 it passed dt_binding_check and dtbs_check now.
