[edk2-devel] [PATCH edk2-platforms 1/4] IpmiFeaturePkg/ServerManagementLib: Support Standalone MM

["Xu, Wei6" <wei6.xu@intel.com>]

Split the ServerManagementLib.c into two source files:
- ServerManagementELog.c to support Event Log functions.
- ServerManagementTime.c to support GetTimeStamp function.
  - Replace gBS->Stall() with MicroSecondDelay() in TimerLib to
remove dependency on gBS.

Base Lib includes both of the two source files, StandaloneMm Lib only
includes the ServerManagementTime.c
