[U-Boot] [PATCH v2] serial: mxc: Add compatibles to NXP's serial driver (for imx21 and imx53)

[sbabic at denx.de]

> This patch fixes not enabled uart2 (and hence serial console) on i.MX53
> devices. After following commit 1d255904c306 ("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 commit 98d62e618bb9 ("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).
