phy: exynos5-usbdrd: fix clock prepare imbalance

Commit f4fb9c4d7f94 ("phy: exynos5-usbdrd: allow DWC3 runtime suspend
with UDC bound (E850+)") incorrectly added clk_bulk_disable() as the
inverse of clk_bulk_prepare_enable() while it should have of course
used clk_bulk_disable_unprepare(). This means incorrect reference
counts to the CMU driver remain.

Update the code accordingly.
