Luca Ceresoli 9c0d2c3f7f fpga: fpga-mgr: xilinx-spi: fix error messages on -EPROBE_DEFER ...

[ Upstream commit 484a58607a ]

The current code produces an error message on devm_gpiod_get() errors even
when the error is -EPROBE_DEFER, which should be silent.

This has been observed producing a significant amount of messages like:

    xlnx-slave-spi spi1.1: Failed to get PROGRAM_B gpio: -517

Fix and simplify code by using the dev_err_probe() helper function.
