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

[Li Yang]

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.
