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 the calls to clk_disable_unprepare().

-v4:
 *Use struct dev *dev to replace &pdev->dev to further simplify
  the code according to Andy Shevchenko.
 *Use HZ_PER_KHZ to replace 1000 according to Andy Shevchenko.
 *Add or reduce blank lines in some places to make the code more
  compliant as suggested by Andy Shevchenko.

-v3:
 *Add another patch to use dev_err_probe() in jz4780_i2c_probe()
  according to Biju and Paul.

-v2:
 *drop sclk from struct em_i2c_device according to Biju.

  i2c: emev2: Use devm_clk_get_enabled() helpers
  i2c: jz4780: Use devm_clk_get_enabled() helpers
  i2c: jz4780: Use dev_err_probe()
