Add acpi_fixup() api in bsp that can override platform ACPI info when
do init_bsp(), this is useful when platform bootloader is not lock

If CONFIG_CONSTANT_ACPI is true, then the value in host_acpi_info structure
is constant. Otherwise the host_acpi_info value could be overrided.
This is useful when platform ACPI table value is not fixed in Bootloader

In production release, this config should be set to yes.

There are some massages which is not fatal error but should to print
to serial and sbuf(hvlog) at the same time. pr_fatal is for fatal error
massages and it is not good choice for the situation above.
Introduce a new API pr_acrnlog to deal with the situation. And replace the
following printf with pr_acrnlog for massages should be print to sbuf and
serial. Then developers can get those massages on serial and BTM(Boot Time
Measurement) can use acrnlog to get those massages from sbuf.
BTM refers to Boot Time Measurement which will read acrnlog file to get
timestamps of steps we want.

When we create an UOS, we didn't indicate the vmid.
Thus we can't get the vm description for the vm
description array.
Instead we use a temporary vm description to save data to
fill the vm structure when crate an UOS. It's uselesss once
UOS has created. So we don't need to maintain vm description

V2->V3: Fixed the booting issue on MRB board and removed the restriction
of allocate memory from address 0
1) Fix the booting from MRB issue
-#define CONFIG_LOW_RAM_SIZE 0x000CF000
+#define CONFIG_LOW_RAM_SIZE 0x00010000
2) changed e820_alloc_low_memory() to handle corner case of unaligned e820 entries
and enable it to allocate memory at address 0
+ a length = end > start ? (end - start) : 0;
- /* We don't want the first page */
- if ((length == size) && (start == 0))
- continue;
3) changed emalloc_for_low_mem() to enable to allocate memory at address 0
- /* We don't want the first page */
- if (start == 0)
- start = EFI_PAGE_SIZE;
V1->V2: moved e820_alloc_low_memory() to guest.c and added the logic to
handle unaligned E820 entries
emalloc_for_low_mem() is used if CONFIG_EFI_STUB is defined.
e820_alloc_low_memory() is used for other cases
In either case, the allocated memory will be marked with E820_TYPE_RESERVED

V1->V2: removed CONFIG_LOW_RAM_START and added ".org 0" to

The assumption is trampoline code is relocated while HV is not, so:
trampoline code is built at address 0, and CS register is updated
by SIPI to reflect the correct vector
in real mode part, added extra pointers for page tables and long jump buffer
so it's possible for HV code to patch the relocation offset
in long mode part, use absolute addressing when referring HV symbols,
and use relative addressing for symbols within trampoline code
