serial: mxc: Add compatibles to NXP's serial driver (for imx21 and imx53)
This patch fixes not enabled uart2 (and hence serial console) on i.MX53 devices. After following commit1d255904c3
("ARM: dts: imx: imx53: Synchronize iMX53 DT with Linux") from the uart2 compatible the 'fsl,imx7d-uart' has been removed (which was correct). However, the root cause of the problem was the commit98d62e618b
("arm: imx: add i.MX53 Beckhoff CX9020 Embedded PC") which introduced this compatible. Moreover, without this patch all i.MX53 UARTs are not usable as neither 'fsl,imx53-uart' nor 'fsl,imx21-uart' are in compatible IDs in drivers/serial/serial_mxc.c file. The fix is to add 'fsl,imx53-uart' and 'fsl,imx21-uart' as compatibles for the aforementioned serial driver (those are also defined in the Linux kernel).
