UefiPayloadPkg: Add AARCH64 support

Add basic support for FIT image on the AARCH64 architecture, reuse exsitting DSC and FDF files for IA32, X64 and AARCH64 architectures. Introduce new PCD: PcdUseUniversalPayloadSerialPort to indicate which serial port module is used due to some serial port parameters are fixed for ARM SoC and Platform. Please use following command to build AARCH64 UPL FIT image: " export GCC5_AARCH64_PREFIX=aarch64-linux-gnu- python UefiPayloadPkg/UniversalPayloadBuild.py -a AARCH64 -t GCC5 -b DEBUG --Fit " Signed-off-by: Amos Bu <[email protected]> Signed-off-by: Ajan Zhong <[email protected]>
