drm/amdgpu: Add guest driver CUID support
v3:
improve the coding style.
v2:
use debugfs_create_x64 and debugfs_create_x8 to create node.
v1:
1. Add guest driver CUID support
2. Do not expose vf index(variable "fcn_idx") to customers,
replace the fcn_idx with pad.
Only expose the unitid to customers.
background:
Change fcn_idx to pad, VF index won't expose to guest vm.
Introduce a new unitid field as the VF identifier to replace the VF index:
1).unitid is assigned by the host driver
2).It is delivered to the guest via the pf2vf message
3).The application or umd can retrieve united from the sysfs node
