Add UFS host controller support for NVIDIA Tegra264 SoCs. The controller
supports UFS 3.1 up to HS-G4B on two data lanes.

This series depends on the Tegra264 M-PHY series: the binding example
uses include/dt-bindings/phy/nvidia,tegra264-mphy.h, and
drivers/ufs/host/Kconfig selects PHY_TEGRA_MPHY. The driver itself has
no build dependency on the M-PHY driver; it consumes the generic PHY
API.
