net: dwc_eth_qos: Fix needless phy auto-negotiation restarts

Disabling clk_ck clock leads to link up status loss in phy, which
leads to auto-negotiation restart before each network command
execution.

This issue is especially big for PXE boot protocol because of
auto-negotiation restarts before each configuration filename trial.

To avoid this issue don't disable clk_ck clock after it was enabled.
