[igt-dev] [PATCH V4 i-g-t 2/3] lib/amdgpu: add apu check for pciplug test

[Jesse Zhang <jesse.zhang@amd.com>]

It is integrated with cpu,
for APU(Accelerated Processing Unit CPU + iGPU).
So hotplug test should be unnecessary for it.

V4:
 - place the APU check in particular subtests.(Kamil)
 - Add igt_info about skipping tests (Vitaly)
