arm64: dts: ti: k3-am625-verdin: add PCIe reset gpio hog
Add a GPIO hog to release PCIe reset on the carrier board, this is
required to use M.2 or mPCIe cards.
Verdin AM62 does not have any PCIe interface, however the Verdin family
has PCIe and normally an M.2 or mPCIe slot is available in the carrier
board that can be used with cards that use only the USB interface toward
the host CPU, for example cellular network modem.
