gpio: of: fix Freescale SPI CS quirk handling
On the gta04 we see: spi_gpio: probe of spi_lcd failed with error -2 The quirk introduced in commite3023bf806
("gpio: of: Handle the Freescale SPI CS") can also be triggered by a temporary -EPROBE_DEFER and so "convert" it to a hard -ENOENT. Disable that conversion by checking for -EPROBE_DEFER. Fixes:e3023bf806
