dt-bindings: trivial-devices: add fsl,mc1323

Add freescale 2.4 GHz IEEE® 802.15.4/ZigBee mc1323 to fix the below
CHECK_DTBS warnings.
  arch/arm/boot/dts/nxp/imx/imx53-smd.dtb: /soc/bus@50000000/spba-bus@50000000/spi@50010000/mc1323@0: failed to match any schema with compatible: ['fsl,mc1323']

Since the i.MX53 platform is more than 20 years old, it is difficult to
find detailed information about how the MC1323 was used on the i.MX53 SMD
board, as the functionality depended on firmware.
