serial: sirf: Use generic uart-has-rtscts DT property
Convert the SiRF UART driver from using the vendor-specific "sirf,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 deprecated.
