drm/amdgpu: Add vbios info ioctl interface
Add AMDGPU_INFO_VBIOS_INFO subquery id for detailed vbios info.
Provides a way for the user application to get the VBIOS
information without having to parse the binary.
It is useful for the user to be able to display in a simple way the VBIOS
version in their system if they happen to encounter an issue.
V2:
Use numeric serial.
Parse and expose vbios version string.
V3:
Remove redundant data in drm_amdgpu_info_vbios struct.
V4:
64 bit alignment in drm_amdgpu_info_vbios.
v5: squash together all the reverts, etc. (Alex)
