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 v8:
- Send proper patchset this time.

Changes since v7:
- Rebased on top of phy/next
- Renamed the clock registration function (Johan)
- Dropped rogue qcom_qmp_ufs_ops (Johan)
- Fixed the comment following Johan's suggestion.

Changes since v6:
- Added bindings change (Johan, thanks for the reminder)
- Added corresponding dts changes for msm8996 and sm8350/sm8450.

Changes since v5:
- Rebased on top of phy/next

Changes since v4:
- Rebased, dropping merged clk patches
- Fixed whitespace errors
- Added linebreaks to fit into 100 chars limit

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).
