[mips] Kill 'support' for untested EABI.

Summary:
There are no llvm backend tests* for EABI and no EABI buildbots. There were only
three clang tests, all of which checked that -mabi=eabi was passed to the
assembler.

*There is a single backend test that specifies EABI but it actually tests MIPS16.
