Linux framebuffer screen_info has been extended to support 64bit
address. This patch added extra fields and set the upper 32 bit
for the framebuffer base.

Recent Linux kernel accepts acpi_rsdp=0x.. in kernel command line.
This will make Linux kernel look for ACPI RSDP address in the kernel
commad line first prior to in DMI or F-segment.

* [QEMU] Enable Stage1A boot in X64 mode
This patch added necessary changes to enable QEMU boot through
Stage1A in SBL X64 build.

* [QEMU] Enable QEMU Linux boot in X64 mode
This patch enabled SBL X64 boot for Linux. At this moment, since
FSP is still in 32 bit mode, it is required to thunk back into
32 bit mode to call FSP APIs.
It fixed#622.

This will allow OsLoader payload to boot to 64-bit kernel entry point.
If CPU supports 64-bit mode and a kernel image has 64-bit entry point,
OsLoader will switch to 64-bit long mode and jump to the 64-bit entry
point. Otherwise, continue to boot to 32-bit entry point.
- Ported necessary code from EDK2 VitualMemory.c in MdeModulePkg
- Moved PagingLib from BootloaderCorePkg to BootloaderCommonPkg
- Removed unused FlushCacheLine
- TBD: 64-bit IDT
Next step is to support 64-bit Payload.
- 32-bit compatible mode
- 64-bit CryptoLib
- etc.

This patch splitted LoadBzImage() into two functions. One is just
for kernel loading. The other one UpdateLinuxBootParams() is for
Linux boot parameter updates. It is required to do so because when
kernel loading in Stage2 is enabled the loading occurs before all
HOBs are finalized. The Linux boot parameters depend on HOBs to fill
correct information, such as frame buffer. With this patch, the boot
parameters can be updated at the very end.

Current SBL code depends on PixelInformation to fill kernel
framebuffer parameters. However, this info is only valid if
PixelFormat is PixelBitMask type. Since FSP will only produce
8bit per pixel format, it is better to use PixelFormat to
determine the pixel bit size and position information. This
patch added this logic. It also fixed#260 .

OsLoader has the capability to boot a Linux kernel. However, to support
LinuxBoot type of payload, it is required to load kernel in Stage2. This
patch abstracts the standard Linux loading logic into common LinuxLib
class so that it can be linked in Stage2 or Payload such as OsLoader.
A new PcdLinuxPayloadEnabled is introduced to control if this feature
should be enabled or not.
To boot a Linux kernel from Stage2, it is required to put the command
line file and kernel image into the EPAYLOAD container during the build.
And the PayloadId CFGDATA needs to be set to 'LINX'.
For example:
python BuildLoader.py build qemu
-p OsLoader.efi::Lz4;vmlinuz:LINX:Dummy;cmdline.txt:CMDL:Dummy
vmlinuz and cmdkube.txt need to be copied to PayloadPkg/PayloadBins
folder. If kernel size cannot fit into EPAYLOAD, EPAYLOAD_SIZE in
BoardConfig.py needs to be adjusted accordingly.
