[igt-dev] [PATCH i-g-t 1/3] lib/drmtest: Add helpers to check and require amdgpu

[Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>]

These helpers will be used to address amdgpu specific quirks and
features. They're implemented like the i915 and VC4 helpers.

In order for the string comparison to pick up "amdgpu" the buffer size
had to be expanded for __is_device. I've gone ahead and made it 12 bytes
to cover everything that's there right now.
