[PATCH v1 net] net: mscc: ocelot: remove buggy duplicate write to DEV_CLOCK_CFG

From: Colin Foster <colin.foster@in-advantage.com>
Date: 2021-09-16 01:24:12

When updating ocelot to use phylink, a second write to DEV_CLOCK_CFG was
mistakenly left in. It used the variable "speed" which, previously, would
would have been assigned a value of OCELOT_SPEED_1000. In phylink the
variable is be SPEED_1000, which is invalid for the
DEV_CLOCK_LINK_SPEED macro. Removing it as unnecessary and buggy.
