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

Browse source

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.
