Subject: [PATCH 02/15] dt-bindings: i2c: imx: update schema to align with original binding

Layerscape SoCs doesn't use ipg as clock name.  Remove the clock name
requirement in the schema.  Also the original binding doesn't enforce
the order of "tx" and "rx" in dma-names.  Both orders are used
extensively in existing dtses, update the schema to allow both.
