Fix VLYNQ device enable for DG834Gv1
This patch allows VLYNQ devices on the DG834Gv1 to be successfully
enabled.
Currently the "__vlynq_enable_device" function attempts to set the VLYNQ
device clock divisor to values from 1 through 8 until a link is
successfully established. On the DG834Gv1 (but not the DG834Gv2),
setting the VLYNQ device clock divisor to 1 (full rate) results in all
further VLYNQ operations failing (including software reset), so the
device is never enabled. This patches changes the function to only
attempt divisors 2 through 8, and hence the device is successfully
enabled.
