Several i.MX boards (all i.MX6 boards) need to do some adjustments
to phy registers. If barebox itself does not use network, networking
won't work in the kernel if the kernel does not have the fixups. Connect
the phy at probe time so that these tweaks are done during probe so that
the kernel works without phy register tweaks. Also this has the effect
that the phy device is present and introspectable without doing fake
network transfers beforehand.

The dump generated by "md -w -s /dev/phy0"
suggests individual registers need to be
addressed by byte offset, not by register number.
E.g. to set the autonegotiation advertisement register
for 10Mbit only, use "mw -w -d /dev/phy0 8+2 0x0061".
The current mix of offset == register number, but
count == byte count is unintuitive.
Also, to be consistent with "md" on /dev/mem, round up
the count so "8+1" also works to access one register.
However, no attempt is made to do read-modify-write
single byte writes.
