Subject: [PATCH v2 06/32] clk: at91: clk-utmi: 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.
