fs_enet: cleanup clock API use
make the Freescale ethernet driver get, prepare and enable the FEC clock
during probe(); disable and unprepare the clock upon remove(), put is
done by the devm approach; hold a reference to the clock over the period
of use.
clock lookup is non-fatal as not all platforms provide clock specs in
their device tree; failure to enable specified clocks is fatal.
