PCI: kirin: Fix reset gpio name

BugLink: http://bugs.launchpad.net/bugs/1794889
[ Upstream commit 5db8f8d1099bd93a64a80b609dbcce887327ffc8 ]

As documented in the devicetree bindings (pci/kirin-pcie.txt) and the
reset gpio name must be 'reset-gpios'. However, current driver
erroneously looks for a 'reset-gpio' resource which makes the driver
probe fail. Fix it.
