From: Claudiu Beznea <claudiu.beznea@tuxon.dev>
Use struct clk_parent_data instead of parent_hw for the main clock
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. This will lead in the end at removing
__clk_get_hw() in SoC specific drivers
(that will be solved by subsequent commits).

[ryan.wanner@microchip: Add SAMA7D65 and SAM9X75 SoCs to use parent_data.]
