From: Tien Fong Chee <tien.fong.c...@intel.com>

On the Arria10, the EMAC phy mode configuration for each EMACs is located
in separate registers versus being in 1 register for the GEN5 devices. The
Arria10 also has 3 EMACs compared to 2 for the GEN5 devices.

Update the dwmac_deassert_reset function to support both GEN5 and Arria10
devices.
