[PATCH v2 11/14] spi: rspi: Convert to clk_prepare_enable/disable_unprepare

[Geert Uytterhoeven <geert-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org>]

From: Geert Uytterhoeven <geert+renesas-Td1EMuHUCqxL1ZNQvxDV9g@public.gmane.org>

Get the driver ready for the migration to the common clock framework by
calling clk_prepare_enable() and clk_disable_unprepare().
