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().

While at it, no need to save clk pointer, drop sclk from struct
em_i2c_device.

-v3:
 *Add another patch to use dev_err_probe() in jz4780_i2c_probe().

-v2:
 *Add another patch to drop sclk from struct em_i2c_device.
