Subject: [PATCH v2 08/32] clk: at91: clk-programmable: use clk_parent_data

From: Claudiu Beznea <claudiu.beznea@...on.dev>

Use struct clk_parent_data instead of struct parent_hw as this leads
to less usage of __clk_get_hw() in SoC specific clock drivers and simpler
conversion of existing SoC specific clock drivers from parent_names to
modern clk_parent_data structures.

[ryan.wanner@...rochip.com: Remove SoC specific changes those will be
added in a separate commit.]
