27	  AMD MP2 STB function provides a data buffer used to log debug
28	  information about the system execution during S2Idle suspend/resume.
29	  A data buffer known as the STB (Smart Trace Buffer) is a circular
30	  buffer which is a low-level log for the SoC which is used to debug
31	  any hangs/stalls during S2Idle suspend/resume.
32
33	  Creates debugfs to get STB, a userspace daemon can access STB log of
34	  last S2Idle suspend/resume which can help to debug if hangs/stalls
35	  during S2Idle suspend/resume.
