eth: asix88179: reset during probe

In some cases (consistently in my case with an embedded board) the
ethernet controller will time out on the first init but always succeed
after reset.

Let's reset the controller during probe so we always start with it in a
known state, and don't have wait for the first asix_wait_link() to
time out.
