Previously we use Kconfig of DMAR_PARSE_ENABLED to choose pre-defined DMAR info
or parse it at runtime, at the same time we use MACRO of CONFIG_CONSTANT_ACPI
to decide whether parse PM related ACPI info at runtime. This looks redundant
so use a unified ACPI_PARSE_ENABLED Kconfig to replace them.

currently, ACRN hypervisor can either boot from sbl/abl or uefi, that's
why we have different firmware method under bsp & boot dirs.
but the fact is that we actually have two different operations based on
different guest boot mode:
1. de-privilege-boot: ACRN hypervisor will boot VM0 in the same context as
native(before entering hypervisor) - it means hypervisor will co-work with
ACRN UEFI bootloader, restore the context env and de-privilege this env
to VM0 guest.
2. direct-boot: ACRN hypervisor will directly boot different pre-launched
VM(including SOS), it will setup guest env by pre-defined configuration,
and prepare guest kernel image, ramdisk which fetch from multiboot modules.
this patch is trying to:
- rename files related with firmware, change them to guest vboot related
- restruct all guest boot stuff in boot & bsp dirs into a new boot/guest dir
- use de-privilege & direct boot to distinguish two different boot operations
this patch is pure file movement, the rename of functions based on old assumption will
be in the following patch.

To merge the multiboot bootargs within sbl_init_vm_boot_info(), buffer
overflow could happen when it doesn't provide correct 'dmax' argument
to strncpy_s().
Also, currently it doesn't check the availability of the dest buffer before
overwriting '\0' with a whitespace, which theoretically the dest string
could end up with no null terminator within it's array boundary.
This patch also creates a separate function to merge the cmdline strings,
because after the above fixes some lines in sbl_init_vm_boot_info()
function could have up to 7 tabs in front of the first character, which
looks messy and sbl_init_vm_boot_info() is getting too complicated.

strncpy_s(d, dmax, s, slen): the 'dmax' includes the null terminator, while
slen doesn't. Thus if (dmax == slen == strlen(s)), strncpy_s() chooses to
discard the last character from s and instead write '\0' to d[dmax - 1].
strnlen_s(s, maxsize): if there is no terminating null character in the
first maxsize characters pointed to by s, strnlen_s() returns maxsize.
So in the following example or similar cases, we need to increase the size
of d[] by 1 to accommodate the null terminator, and add '1' to the dmax
argument to strncpy_s().
uint8_t d[MAX_LEN];
size = strnlen_s(s, MAX_LEN);
strncpy_s(d, MAX_LEN, s, size);

bootargs_load_addr (GPA) and zero page which locates at one page follows it:
- SOS: currently it's fixed at 0x24EFC000. Theoretically, this address may
not exist if the system has small memory size.
- pre-launched VMs: currently it's at (vm_config->memory.size - 8KB).
It doesn't work if the guest has been assigned for more than 4GB memory
size, because zero page must be under 4GB.
- This patch reserves 8KB for bootargs_load_addr right before kernel_load_addr
for either SOS or pre-launched VMs.
ramdisk_load_addr (GPA):
- pre-launched VMs: currently it doesn't allow ramdisk.
- SOS: currently it's assigned at mods[].mm_mod_start. It's a bug because it
misses the hpa2gpa() conversion.
- This patch puts ramdisk_load_addr right after (kernel_load_addr + kernel_size),
which has 2 benefits:
- for pre-launched VMs, mods[].mm_mod_start may be out of its GPA range.
- it may be better to consolidate everything (bootarg, kernel, ramdisk) in
consecutive GPA, other than spread them out in different places.

Per ACPI spec, there are two fundamental types of ACPI tables:
Tables that contain AML code produced from the ACPI Source Language (ASL).
These include the DSDT, any SSDTs, and sometimes OEM-specific tables (OEMx).
Tables that contain simple data and no AML byte code. These types of tables
are known as ACPI Data Tables. They include tables such as the FADT, MADT,
ECDT, SRAT, etc. -essentially any table other than a DSDT or SSDT.
The second type of table, the ACPI Data Table, could be parsed here.
If Kconfig of CONSTANT_ACPI is set to yes, this parser is not needed.
