    usb: host: xhci-tegra: Add Tegra234 XHCI support

    This change adds Tegra234 XUSB host mode controller support.

    In Tegra234, some of the registers have moved to bar2 space.
    The new soc variable has_bar2 indicates the chip with bar2
    area. This patch adds new reg helper to let the driver reuse
    the same code for those chips with bar2 support.
