There are other NXP NCI compatible NFC controllers such as the PN7150
that use an integrated firmware and therefore do not have a GPIO to
select firmware downloading mode. To support these kind of chips,
let's make the firmware GPIO optional.

...

-       gpiod_set_value(phy->gpiod_fw, (mode == NXP_NCI_MODE_FW) ? 1 : 0);
+       if (phy->gpiod_fw)
+               gpiod_set_value(phy->gpiod_fw, (mode == NXP_NCI_MODE_FW) ? 1 : 0);

This change is not needed.
