dt-bindings: crypto: Convert Atmel SHA to yaml
Convert Atmel SHA documentation to yaml format. With the conversion the
clock and clock-names properties are made mandatory. The driver returns
-EINVAL if "sha_clk" is not found, reflect that in the bindings and make
the clock and clock-names properties mandatory. Update the example to
better describe how one should define the dt node.
