arm: socfpga: misc: Add proper ethernet initialization
Add function to initialize the EMAC blocks upon board startup.
The preprocessor guards against building on SoCFPGA-VT and against
SPL build are not needed as those are handled implicitly via both
SPL framework and the socfpga_cyclone5.h config file, which will
not define CONFIG_DESIGNWARE_ETH if building for SoCFPGA-VT.
We cannot handle two EMAC ethernet blocks yet, therefore the ifdefs.
Once there is hardware using both EMAC blocks, this ifdef will have
to go.
