gpio: mb86s7x: Use helper function devm_clk_get_optional_enabled()

Browse Source 
devm_clk_get_optional() and clk_prepare_enable() can be replaced by helper
function devm_clk_get_optional_enabled(). Let's simplify code with use of
devm_clk_get_optional_enabled() and avoid calling clk_disable_unprepare().
