[-next] bus: imx-weim: Use devm_clk_get_enabled() helper function

Commit Message

Jinjie Ruan Aug. 25, 2023, 7:19 a.m. UTC

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

This simplifies the code.
