Before referencing to physical address of devs such as lapic, ioapic,
vtd, and uart, switch to virtual address.
Use a phisical address of pml4 to write CR3.

Before this patch, guest temporary page tables were generated by hardcode
at compile time, HV will copy this page tables to guest before guest
launch.
This patch creates temporary page tables at runtime for the range of 0~4G,
and create page tables to cover new range(511G~511G+16M) with trusty
requirement.

Per SDM Vol. 2:
If CPUID.80000008H:EAX[7:0] is supported, the maximum physical address
number supported should come from this field.
This patch gets the maximum physical address number from CPUID leaf
0x80000008 and calculates the physical address mask when the leaf is
available.
Currently ACRN does not support platforms w/o this leaf and will panic
on such platforms.
Also call get_cpu_capabilities() earlier since the physical address mask
is required for initializing paging.

According to C99:
The empty list in a function declarator that is not part of a definition of
that function specifies that no information about the number or types of the
parameters is supplied.
This means gcc is happy with the following code, which is undesirable.
void foo(); /* declaration with an empty parameter list */
void bar() {
foo(); /* OK */
foo(1); /* OK */
foo(1, 2); /* OK */
}
This patch fixes declarations of functions with empty parameter lists by adding
an unnamed parameter of type void, which is the standard way to specify that a
function has no parameters. The following coccinelle script is used.
@@
type T;
identifier f;
@@
-T f();
+T f(void);
New compilation errors are fixed accordingly.

Add 'CPU_PAGE_MASK' used for calculate address,
Change IA32E_REF_MASK from 0x7ffffffffffff000 to 0x000ffffffffff000
for MMU/EPT entry, bit62:52(ignore) bit63(VE/XD)
if we want to obtain the address from the MMU/EPT entry,need to clear
bit63:52 by IA32E_REF_MASK
