ARM: tegra: fix USB ULPI PHY reset signal inversion confusion
USB ULPI PHY reset signals are typically active low. Consequently, they should be marked as GPIO_ACTIVE_LOW in device tree, and indeed they are in the Linux kernel DTs, and in DT properties that U-Boot doesn't yet use. However, in DT properties that U-Boot does use, the value has been set to 0 (== GPIO_ACTIVE_HIGH) to work around a bug in U-Boot. This change fixes the DT to correctly represent the HW, and fixes the Tegra USB driver to cope with the fact that dm_gpio_set_value() internally handles any inversions implied by the DT value GPIO_ACTIVE_LOW.
