Document already upstreamed and used Qualcomm SC7180 UFS host controller
to fix dtbs_check warnings like:

  sc7180-idp.dtb: ufshc@1d84000: clocks: [[39, 99], [39, 7], [39, 98], [39, 107], [36, 0], [39, 106], [39, 105]] is too short
  sc7180-idp.dtb: ufshc@1d84000: clock-names: ['core_clk', 'bus_aggr_clk', 'iface_clk', 'core_clk_unipro', ...] is too short
