[PATCH 2/5] usb: pxa27x_udc: Use devm_clk_get_enabled() helpers

[Lei Liu]

The devm_clk_get_enabled() helpers:
    - call devm_clk_get()
    - call clk_prepare_enable() and register what is needed in order to
     call clk_disable_unprepare() when needed, as a managed resource.

This simplifies the code and avoids calls to clk_disable_unprepare().
