serial: mxs-auart: Use generic uart-has-rtscts DT property

Convert the Freescale MXS AUART driver from using the vendor-specific
"fsl,uart-has-rtscts" to the generic "uart-has-rtscts" DT property, as
documented by the Generic Serial DT Bindings.

The old vendor-specific property is still recognized by the driver for
backwards compatibility, but it is deprecated.

Optional properties:
- fsl,uart-has-rtscts : Indicate the UART has RTS and CTS lines
- uart-has-rtscts : Indicate the UART has RTS and CTS lines
for hardware flow control,
it also means you enable the DMA support for this UART.
