print firmware versions on amdgpu sysfs

[Deucher, Alexander]

We also expose the firmware versions via ioctl which is what the UMDs uses.  If you'd prefer it in sysfs, we could do that too.

Hi Alex,

Currently we retrieve firmware versions from /sys/kernel/debug but this
requires debugfs being enabled and superuser privilege. Do you see a
concern we add firmware versions to amdgpu sysfs at
/sys/class/drm/cardX/device like vbios_version?

Regards,
Amber
