dt-bindings: crypto: Convert Marvell CESA to DT schema

Convert the Marvell CESA binding to DT schema format. The
marvell-cesa.txt and mv_cesa.txt are duplicate bindings.

The clock properties are quite varied for each platform hence the
if/then schemas. The old binding was fairly accurate with reality.

The original binding didn't mention there is 1 interrupt per CESA
engine. Based on users, there's a maximum of 2 engines.
