net: ethernet: arc: remove emac_arc driver

Browse Source 
The last real user nSIM_700 of the "snps,arc-emac" compatible string in
a driver was removed in 2019. The use of this string in the combined DT of
rk3066a/rk3188 as place holder has also been replaced, so
remove emac_arc.c to clean up some code.

On some legacy ARC (Synopsys) FPGA boards such as ARCAngel4/ML50x
non-standard on-chip ethernet device ARC EMAC 10/100 is used.
Say Y here if you have such a board. If unsure, say N.
