[PATCH v7 3/4] clk: qcom: lcc-ipq806x: convert to parent data
From: Christian Marangi
Date: Sun Jul 24 2022 - 14:24:09 EST
Convert lcc-ipq806x driver to parent_data API.
Change parent_name for pll4 to pxo_board to prepare the future to
eventually drop the double pxo board clk.

---
v7:
- Add info about changed pxo clk
- Add review tag
v6:
- Split to separate patch for ARRAY_SIZE
- Rename .name to pxo_board
- Drop _clk from .fw_name
v5:
- Fix the same compilation error (don't know what the hell happen
to my buildroot)
v4:
- Fix compilation error
v3:
- Inline pxo pll4 parent
- Change .name from pxo to pxo_board
