[igt-dev] [PATCH i-g-t 04/11] tests/amdgpu/amd_plane: Switch mpo-swizzle-toggle to single-head

[Stylon Wang]

From: Victor Lu <victorchengchi.lu at amd.com>

[why]
Older ASIC does not support multi-head MPO

[how]
Rename current mpo-swizzle-toggle subtest to
mpo-swizzle-toggle-multihead. Change mpo-swizzle-toggle to only use one
output.
