[PATCH 3/3] dt-bindings: ufs: qcom: Document HS gear and rate limit properties

[Ram Kumar Dwivedi]

Add documentation for two new optional properties:
  - limit-hs-gear
  - limit-rate

These properties allow platforms to restrict the maximum high-speed
gear and rate used by the UFS controller. This is required for
certain automotive platforms with hardware constraints.
