Register UFS symbol clocks in the Qualcomm QMP PHY driver. Some of the
platforms (msm8996, sc7280, sm8350/sm8450) expect them to be defined (to
be used as GCC clock parents).

Changes since v3:
- Rewrote asm9260 clk driver to fix the TODO item by using parent index
  rather than calling of_clk_get_parent_name().

Changes since v2:
- Added error handling to phy_symbols_clk_register() (requested by
  Johan).

Changes since v1:
- Added a macro used by clk-asm9260, so that the clk-fixed-rate changes
  do not affect the driver
- Changed registered clock names to be unique (as e.g. SC8280XP will
  have two UFS PHYs).

Dmitry Baryshkov (3):
  clk: asm9260: use parent index to link the reference clock
  clk: fixed-rate: add devm_clk_hw_register_fixed_rate
  phy: qcom-qmp-ufs: provide symbol clocks
