memory: mvebu-devbus: Fix missing clk_disable_unprepare in mvebu_devbus_probe()

[ Upstream commit cb8fd6f75775165390ededea8799b60d93d9fe3e ]

The clk_disable_unprepare() should be called in the error handling
of devbus_get_timing_params() and of_platform_populate(), fix it by
replacing devm_clk_get and clk_prepare_enable by devm_clk_get_enabled.
