arm64: dts: hisilicon: poplar: Correct PCIe reset GPIO polarity

commit c1f2b0f2b5 upstream.

The PCIe reset GPIO on Poplar is actually active low.  The active high
worked before because kernel driver didn't respect the setting from DT.
This is changed since commit 1d26a55fbe ("PCI: histb: Switch to using
gpiod API"), and thus PCIe on Poplar got brken since then.

Fix the problem by correcting the polarity.
