Commit 3752e453f6ba ("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.
