[PATCH -next 09/11] gpio: stp-xway: Use helper function devm_clk_get_enabled()

[Li Zetao]

Since commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for
prepared and enabled clocks"), devm_clk_get() and clk_prepare_enable()
can now be replaced by devm_clk_get_enabled() when the driver enables
(and possibly prepares) the clocks for the whole lifetime of the device.
Moreover, it is no longer necessary to unprepare and disable the clocks
explicitly.
