net: dwc_eth_qos: Add support for platform specific reset

Browse Source 
This patch adds support for optional platform specific reset logic in
the dwc_eth_qos driver. This new function 'eqos_fix_soc_reset' is called
after the EQOS_DMA_MODE_SWR is set and before the driver waits for this
bit to clear.
