driver: net: fsl-mc: remove MC firmware version check

The MC version numbers provide no meaningful information
about binary interface compatibility, so remove the
check which refuses to start the MC unless a specific
version is found.

Version checking is supposed to be done at the individual
object level, and individual drivers are responsible
for their own version checking.
