memory: atmel-sdramc: Fix missing clk_disable_unprepare in atmel_ramc_probe()

[ Upstream commit 340cb392a038cf70540a4cdf2e98a247c66b6df4 ]

The clk_disable_unprepare() should be called in the error handling
of caps->has_mpddr_clk, fix it by replacing devm_clk_get and
clk_prepare_enable by devm_clk_get_enabled.
