Subject: [PATCH] dt-bindings: serial: fsl-imx-uart: fix i.MX 53 and 6 compatible matching

The i.MX 53 and i.MX6Q DTS use two compatibles, i.MX 6SL/6SLL/SX three
so update the binding to fix dtbs_check warnings like:

  serial@...c000: compatible: ['fsl,imx6q-uart', 'fsl,imx21-uart'] is not valid under any of the given schemas
