net: dwc: add a common empty ops eqos_null_ops

Browse source 
Add a common empty ops: eqos_null_ops() to remove the duplicated empty
functions and reduce the driver size for stm32 and imx config.

This patch also aligns the prototype of ops 'eqos_stop_clks' with other
eqos ops by adding return value.
