fec_mxc: Remove CONFIG_FEC_FIXED_SPEED support

Browse source 
This option is only used on one platform currently. However, with PHYLIB
enabled, which this platform also does, this option is not checked and
the functional use case is handled. Remove this code.

Optional, selects the exact phy address that should be connected
and function fecmxc_initialize will try to initialize it.
CONFIG_FEC_FIXED_SPEED
Optional, selects a fixed speed on the MAC interface without asking some
phy. This is usefull if there is a direct MAC <-> MAC connection, for
example if the CPU is connected directly via the RGMII interface to a
ethernet-switch.
Reading the ethaddr from the SoC eFuses:
if CONFIG_FEC_MXC is defined and the U-Boot environment does not contain the
ethaddr variable, then its value gets read from the corresponding eFuses in
