[edk2] [PATCH V3 11/17] IntelFspPkg/BaseFspDebugLibSerialPort: Add new APIs

2019-03-19 Thread Zhichao Gao
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1395

Add new APIs' implementation (DebugVPrint, DebugBPrint)
in the DebugLib instance. These APIs would expose print
routines with VaList parameter and BaseList parameter.
