[PATCH] dt-bindings: firmware: cznic,turris-mox-rwtm: convert to DT schema

[Gabor Juhos]

Convert the Turris Mox rWTM firmware binding to YAML format. Both the
compatibles and the examples were adjusted to match with the ones used
by the existing device trees to avoid new dtb check warnings.

-Required properties:
- - compatible		: Should be "cznic,turris-mox-rwtm"
- - mboxes		: Must contain a reference to associated mailbox
-
-This device tree node should be used on Turris Mox, or potentially another A3700
-compatible device running the Mox's rWTM firmware in the secure processor (for
-example it is possible to flash this firmware into EspressoBin).

-			mboxes = <&rwtm 0>;
-			status = "okay";
