[PATCH i-g-t 0/8] dmem: add amdgpu support and one more test

[Thadeu Lima de Souza Cascardo <cascardo@igalia.com>]

This work builds on top of Thomas Hellström's patches at [1].

Besides the case of eviction when setting dmem.max, which still needs
support from [2], there are other cases for testing dmem behavior and
potential regressions. Thomas' patches lay over the groundwork for this,
while this patchset addes one basic test of checking current usage and that
drivers respect max setting when no eviction is taking place yet.

This patchset also introduces a driver layer such that the same tests can
work with different drivers. amdgpu support is here added too.
