[PATCH v2 10/32] clk: at91: clk-usb: add support for clk_parent_data

[<Ryan.Wanner@microchip.com>]

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

Add support for clk_parent_data in usb clock driver.

All the SoC based drivers that rely on clk-usb were adapted
to the new API change. The switch itself for SoCs will be done
in subsequent patches.
