Michael Hennerich 73e1ac1625 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.
