Add fundamental AARCH64 architecture FIT image support, introduce
new dsc and fdf files for AARCH64 architecture, and introduce new
PCD: PcdUseUniversalPayloadSerialPort to indicate which serial
port component is used due to some serial port parameters are fixed
for ARM SoC and Platform.

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 -c UefiPayloadPkg/UefiPayloadPkg_aarch64.dsc --Fit
"

Serial port and Graphic device nodes will be parsed only when 'pci-rb'
node is compatible to 'pci-rb' type in current logic, this logic limits
bootloader to provide informations of all Host PCI Root Bridges.

However, PciHostBridgeLib library in UefiPayloadPkg provides support
to scan Host PCI Root Bridges dynamically. Bootloader can utilizes
Root Bridges scanning feature, and provides Serial Port and Graphic
device information in a 'pci-rb' node without providing informations
about all Host PCI Root Bridges.

refine gaphic and serial

Add Red/Green/Blue mask and pixelsperscanline properties parse
when constructing GraphicInfo HoB, these properties are required
during flash Framebuffer data to Graphic device.

DO NOT MERGE!!

If unaligned check has been enabled in ARM64 platform, FDT parser might
dereference unaligned address to get 64-bit data. Use unaligned data
read to avoid triggering unaligned data access

According to ACPI Specification, 64 bit physical address of the XSDT
provides indentical functionality to the RSDT but accommodates phiscal
address of description headers that are larger than 32 bits.

In this case physical address of XSDT table is 64 bit aligned, however
size of ACPI description tabled header is not 64 bit alinged. It leads
to the entry of other description headers are not 64 bit aligned. In
ARM64 architecture, deference not 64 bit aligned address to get 64 bit
data will trigger unaligned data access fault. Use ReadUnaligned64
method to fix this unaligned data access issue.

SR-IOV is enabled for NVME device, it is impossible to disable
controller for the first node, so we need to wait till timeout.

During this timeout period, prompt message to indicate status.
