[PATCH v2 0/4] Add UFS host controller support for NVIDIA Tegra264

[Kartik Rajput <kkartik@nvidia.com>]

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 references
the M-PHY provider, and drivers/ufs/host/Kconfig selects PHY_TEGRA_MPHY.
The driver consumes the M-PHY through the generic PHY API.

Changes in v2:
- Rename the UFS functional clock to "core" and the host-consumed UPHY
  PLL clock to "hs" in the binding and driver.
- Use raw M-PHY cell values in the binding example so it can be checked
  independently of the prerequisite series.
- Drop the unnecessary mod_devicetable.h include and clean up the OF
  match table initializers.
- Limit compile testing to 64-bit architectures because the high-speed
  link clock rate exceeds the range of unsigned long on 32-bit systems.
- Tear down the M-PHY lanes in reverse initialization order.
- Link to v1: https://lore.kernel.org/r/20260909-tegra264-ufs-v1-0-e4a9831702a0@nvidia.com
