ACRN didn't support dynamic memory allocation. SO it would reserve
a big page pool and use the GPA as index to get a page to do EPT
mapping. In order to save memory, we put high MMIO windows to [4G, 5G].
AFter we support dynamic page allocation for EPT mapping, we move
high MMIO windows to where it used to ([256G, 512G]) for 39 bits physical
address), we could move high memory to where is used to too ([4G, 4G +
size]).

DM maps 64-bit mmio BARs of vdev into 4G-5G, for post-launched VMs. At native
platform, 64-bit MMIO BARs which have 39-bit address, are always mapped into
256G-512G address space.
Change PCI_EMUL_MEMBASE64 to 256G, change PCI_EMUL_MEMLIMIT64 to 512G. So that
the 64-bit vdev BARs of post-launched VMs have same address space with native
platform.

support PDF generation of the documentation set. This PR refines the
doc build process, cleaning up the Makefile, adding display of tool
version information, and updates the doc building documentation to
include additional dependencies needed for building the PDF and
instructions for how to build the PDF. The latexpdf make target is
provided to just run the latex and PDF producing process that depends on
the HTML artifacts from a make html run. A new make pdf target is
provided that combines the two steps into one.
A new know-issues pattern file is added that verifies the expected

eliminated without losing potential error messages that need to be
resolved.

In order to support platform (such as Ander Lake) which physical address width
bits is 46, the current code need to reserve 2^16 PD page ((2^46) / (2^30)).
This is a complete waste of memory.
This patch would reserve PD page by three parts:
1. DRAM - may take PD_PAGE_NUM(CONFIG_PLATFORM_RAM_SIZE) PD pages at most;
2. low MMIO - may take PD_PAGE_NUM(MEM_1G << 2U) PD pages at most;
3. high MMIO - may takes (CONFIG_MAX_PCI_DEV_NUM * 6U) PD pages (may plus
PDPT entries if its size is larger than 1GB ) at most for:
(a) MMIO BAR size must be a power of 2 from 16 bytes;
(b) MMIO BAR base address must be power of two in size and are aligned with
its size.
