fec: Do not access unexisting register in Coldfire

Commit 55cd48c821de ("net: fec: stop the "rcv is not +last, " error
messages") introduces a write to a register that does not exist in
Coldfire.

Move the FEC_FTRL register access inside the FEC_QUIRK_HAS_RACC 'if' block,
so that we guarantee it will not be used on Coldfire CPUs.
