i2c: synquacer: Fix an error handling path in synquacer_i2c_probe()

If an error occurs after the clk_prepare_enable() call, it should be undone
by a corresponding clk_disable_unprepare() call, as already done in the
remove() function.

As devm_clk_get() is used, we can switch to devm_clk_get_enabled() to
handle it automatically and fix the probe.

Update the remove() function accordingly and remove the now useless
clk_disable_unprepare() call.
