*BaseSmbusLib: (new version)

Browse Source 
Complete function header, detailed description, ASSERT()s & pass smoke test in MRC of Lakeport package by replacing Smbus PPI. 
*Device Patch Lib
Fix a bug in AppendDevicePathNode() (Solve Track #44 in Remodel PVCS). The original logic failed if the first device path was NULL.
*Performance Lib 
Add PeiPerformanceHob & Performance protocol in spd file in EdkModule Package (Solve Tracker #41, #42 in Remodel PVCS).
*Hob Lib
Add detailed description for each Hob function.
