[igt-dev] [PATCH] [i-g-t] tests/amdgpu/amd_dp_dsc: fix test crash signal sigsegv

[Hersen Wu]

array size of data.output is 6. when n_outputs is greater than 6,
test will crash. valid combinations of pipe and output are available
for pipes with display->pipes[i].enable = true. macro for_each_pipe
should be used for loop.
