fpga: fpga-mgr: xilinx-spi: fix error messages on -EPROBE_DEFER
[ Upstream commit 484a58607a808c3721917f5ca5fba7eff809e4df ]
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.
