[PATCH v2 04/11] net: dwc_eth_qos: Scrub ifdeffery

[Marek Vasut]

Replace ifdef CONFIG_CLK with if (CONFIG_IS_ENABLED(CLK)) to improve code
build coverage. Some of the functions printed debug("%s: OK\n", __func__);
on exit with and without CLK enabled, some did not, make it consistent and
print nothing if CLK is disabled.
