net: dc2114x: remove the pass all multicast flag in operation mode settings

Remove the OMR_PM flag and choose 16 perfect filtering mode since in
modern networks there're plenty of multicasts and set ORM_PM flag will
increase the dc2114x's workload and ask the U-Boot to handle packets
not related to itself. And most of the time, U-Boot does not need this
feature.
