[PATCH] fpga-manager: altera-ps-spi: preserve nCONFIG state

From: Anatolij Gustschin If the driver module is loaded when FPGA is configured, the FPGA is reset because nconfig is pulled low (low-active gpio inited with GPIOD_OUT_HIGH activates the signal which means setting its value to low). Init nconfig with GPIOD_OUT_LOW to prevent this. Signed-off-by:
