usb: phy: tegra: Include proper GPIO consumer header to fix compile testing

The driver uses only GPIO Descriptor Consumer Interface so include
proper header.  This fixes compile test failures (e.g. on i386):

    drivers/usb/phy/phy-tegra-usb.c: In function ‘ulpi_phy_power_on’:
    drivers/usb/phy/phy-tegra-usb.c:695:2: error:
