PM / tools: scripts: AnalyzeSuspend v4.2

Update AnalyzeSuspend to v4.2:

 - kprobe support for function tracing
 - config file support in lieu of command line options
 - advanced callgraph support for function debug
 - dev mode for monitoring common sources of delay, e.g. msleep, udelay
 - many bug fixes and formatting upgrades
