[PATCH 1/1] pinctrl: mvebu: use devm_clk_get_enabled() in dove_pinctrl_probe()

[Yuanjun Gong <ruc_gongyuanjun@xxxxxxx>]

in dove_pinctrl_probe(), the return value of function
clk_prepare_enable() should be checked, since it may fail.
using devm_clk_get_enabled() instead of devm_clk_get() and
clk_prepare_enable() can avoid this problem.
