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.

The platform which physical-address width over 39 bits must support
1GB large page (Both MMU and VMX sides ). This could save lots of
page table pages for EPT MMIO mapping.

This patch tweaks the settings in doc/conf.py to allow formatting the
documentation to a PDF file by Sphinx. The changes include:
- Use `xelatex` rather than the default `pdflatex` as the LaTeX engine, as
`pdflatex` is not that good at formatting non-ascii characters out of
the box.
- Use DejaVu fonts (which are available in common Linux distributions) in
the generated PDF.
- Restrict the depths of the table of contents to 3.

We used get_mem_range_info to get the top memory address and then use this address
as the high 64 bits max memory address of SOS. This assumes the platform must have
high memory space.
This patch removes the assumption. It will set high 64 bits max memory address of
SOS to 4G by default (Which means there's no 64 bits high memory), then update
the high 64 bits max memory address if the SOS really has high memory space.

Now BSP may launch VMs before APs have not done its initilization,
for example, sched_control for per-cpu. However, when we initilize
the vcpu thread data, it will access the object (scheduler) of the
sched_control of APs. As a result, it will trigger the PF.
This patch would waits each physical has done its initilization before

- Building of any C file depends on $(HV_CONFIG_TIMESTAMP) which indicates

- Source files listed in $(VM_CFG_C_SRCS), which are the generated

With the dependencies above, the build system can now safely be executed in
