drm/amdgpu: Add sysfs file for PCIe usage v5
Add a sysfs file that reports the number of bytes transmitted and
received in the last second. This can be used to approximate the PCIe

v3: Don't make the file on APUs
v4: Early exit for APUs in the read function, change output to
display "packets-received packets-sent mps"
v5: fix missing header for si (Alex)
