hwrng: omap3-rom - fix using wrong clk_disable() in omap_rom_rng_runtime_resume()

Browse source 
[ Upstream commit e4e62bbc6a ]

'ddata->clk' is enabled by clk_prepare_enable(), it should be disabled
by clk_disable_unprepare().

Fixes: 8d9d4bdc49 ("hwrng: omap3-rom - Use runtime PM instead of custom functions")
