Sonic Zhang dc8f3703e7 serial: bfin-sport-uart: Request CTS GPIO PIN when the sport emulated serial device starts up.
This patch is similar to that for bfin-uart hardware flow control.
Sport emulated serial device may be probed earlier before GPIOLIB is initialized.
Requesting and configuring CTS GPIO PIN fails in that early stage.
