spi/bfin_spi: only request GPIO on first load The gpiolib code does not allow people to do gpio_request() on a GPIO once it has already been requested. So make sure we only request the pin on the first setup of a SPI device. Otherwise, if you attempts to reconfigure a SPI device on the fly (like change bit sizes), the setup function incorrectly fails.
