[PATCH v3] clk: qcom: gcc-sc8280xp: add cxo as parent for three ufs ref clks

[PATCH v3] clk: qcom: gcc-sc8280xp: add cxo as parent for three ufs ref clks

[Shazad Hussain]

The three UFS reference clocks, gcc_ufs_ref_clkref_clk for external
UFS devices, gcc_ufs_card_clkref_clk and gcc_ufs_1_card_clkref_clk for
two PHYs are all sourced from CXO.

Added parent_data for all three reference clocks described above to
reflect that all three clocks are sourced from CXO to have valid
frequency for the ref clock needed by UFS controller driver.

Fixes: d65d005f9a6c ("clk: qcom: add sc8280xp GCC driver")
