[PATCH] usb: r8a66597-hcd: Convert to clk_prepare/unprepare

[Simon Horman]

From: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>

Turn clk_enable() and clk_disable() calls into clk_prepare_enable() and
clk_disable_unprepare() to get ready for the migration to the common
clock framework.
