[PATCH 1/2] arm64: dts: clearfog-gt-8k: fix USB regulator gpio polarity

The fixed regulator driver ignores the gpio flags, so this change has
no practical effect in the current implementation. Fix it anyway to
correct the hardware description.

This reset signal controls the Marvell 1512 1G PHY.

Note that current implementation queries the PHY over the MDIO bus
(get_phy_device() call from of_mdiobus_register_phy()) before reset
signal deassert. If the PHY reset signal is asserted at boot time, PHY
registration fails. So current code relies on the bootloader to deassert
the reset signal.
