selftests/powerpc/pmu/ebb: remove fixed_instruction.S

Commit 01cb554af3db ("selftests/powerpc: Add tests of PMU EBBs") added
selftest testcases to verify EBB interface. instruction_count_test.c
testcase needs a fixed loop function to count overhead. Instead of using
the thirty_two_instruction_loop() in fixed_instruction_loop.S in ebb
folder, file is linked with thirty_two_instruction_loop() in loop.S from
top folder. Since fixed_instruction_loop.S not used, patch removes the
file.
