Add the IOCTL interface so that applications can allocate per VM BOs.

Still WIP since not all corner cases are tested yet, but this reduces average
CS overhead for 10K BOs from 21ms down to 48us.

v2: add some extra checks, remove the WIP tag
v3: rename new flag to AMDGPU_GEM_CREATE_VM_ALWAYS_VALID

Add 2 debugfs files, one that contains the VBIOS version, and one that
contains the VBIOS itself. These won't change after initialization,
so we can add the VBIOS version when we parse the atombios information.

This ensures that we can find out the VBIOS version, even when the dmesg
buffer fills up, and makes it easier to associate which VBIOS version is
for which GPU on mGPU configurations. Set the size to 20 characters in
case of some weird VBIOS version that exceeds the expected 17 character
format (3-8-3\0). The VBIOS dump also allows for easy debugging
