[PATCH 1/2] PCI: fu740: fix finding GPIOs

[Ben Dooks]

The calls to devm_gpiod_get_optional() have the -gpios at the end of
the name. This means the pcie driver is not finding the necessary
reset or power GPOOs to allow the PCIe devices on the SiFive Unmatched
boards.

This has not been a noted bug as the PCIe probe from u-boot has been
required to get the PCIe working due to other issues with the system
setup. It could have been broken since the driver inclusion, and not
been noticed as it is not necessary for the driver to funciton.
