Ilya Lipnitskiy 9b54dad28d of: property: fw_devlink: do not link ".*,nr-gpios" 
commit d473d32c2fbac2d1d7082c61899cfebd34eb267a upstream.

[<vendor>,]nr-gpios property is used by some GPIO drivers[0] to indicate
the number of GPIOs present on a system, not define a GPIO. nr-gpios is
not configured by #gpio-cells and can't be parsed along with other
"*-gpios" properties.

nr-gpios without the "<vendor>," prefix is not allowed by the DT
spec[1], so only add exception for the ",nr-gpios" suffix and let the
error message continue being printed for non-compliant implementations.

[0] nr-gpios is referenced in Documentation/devicetree/bindings/gpio:
 - gpio-adnp.txt
 - gpio-xgene-sb.txt
 - gpio-xlp.txt
 - snps,dw-apb-gpio.yaml

[1] Link: cb53a16a1e/schemas/gpio/gpio-consumer.yaml (L20)

Fixes errors such as:
  OF: /palmbus@300000/gpio@600: could not find phandle

Fixes: 7f00be96f1 ("of: property: Add device link support for interrupt-parent, dmas and -gpio(s)")
