ACRN used to prepare the vTPM2 ACPI Table for pre-launched VM at the build stage
using config tools. This is OK if the TPM2 ACPI Table never changes. However,
TPM2 ACPI Table may be changed in some conditions: change BIOS configuration or
update BIOS.
This patch do TPM2 fixup to update the vTPM2 ACPI Table and TPM2 MMIO resource

We should not hardcode the VM ramdisk load address right after kernel
load address because of two reasons:
1. Per Linux kernel boot protocol, the Kernel need a size of
contiguous memory(i.e. init_size field in zeropage) from
its load address to boot, then the address would overlap
with ramdisk;
2. The hardcoded address could not be ensured as a valid address
in guest e820 table, especially with a huge ramdisk;
Also we should not hardcode the VM kernel load address to its pref_address
which work for non-relocatable kernel only. For a relocatable kernel,
it could run from any valid address where bootloader load to.
The patch will set the VM kernel and ramdisk load address by scanning
guest e820 table with find_space_from_ve820() api:
1. For SOS VM, the ramdisk has been loaded by multiboot bootloader
already so set the load address as module source address,
the relocatable kernel would be relocated to a appropriate address
out space of hypervisor and boot modules to avoid guest memory
copy corruption;
2. For pre-launched VM, the kernel would be loaded to pref_address
first, then ramdisk will be put to a appropriate address out space
of kernel according to guest memory layout and maximum ramdisk
address limit under 4GB;

Now ACRN supports direct boot mode, which could be SBL/ABL, or GRUB boot.
Thus the vboot wrapper layer can be removed and the direct boot functions
don't need to be wrapped in direct_boot.c:
- remove call to init_vboot(), and call e820_alloc_memory() directly at the
time when the trampoline buffer is actually needed.
- Similarly, call CPU_IRQ_ENABLE() instead of the wrapper init_vboot_irq().
- remove get_ap_trampoline_buf(), since the existing function
get_trampoline_start16_paddr() returns the exact same value.
- merge init_general_vm_boot_info() into init_vm_boot_info().
- remove vm_sw_loader pointer, and call direct_boot_sw_loader() directly.
- move get_rsdp_ptr() from vboot_wrapper.c to multiboot.c, and remove the
wrapper over two boot modes.

Previously the VM kernel bootargs for pre-launched VMs and direct boot mode
of SOS VM are built-in hypervisor binary so end users have no way to change
it. Now we provide another option that the multiboot module string could be
used as bootargs also. This would bring convenience to end users when they
use GRUB as bootloader because the bootargs could be configurable in GRUB
menu.
The usage is if there is any string follows configured kernel_mod_tag in
module string, the string will be used as new kernel bootargs instead of
built-in kernel bootargs. If there is no string follows kernel_mod_tag,
then the built-in bootargs will be the default kernel bootargs.
Please note kernel_mod_tag must be the first word in module string in any
case, it is used to specify the module for which VM.

Previously sanitize_multiboot_info() was called after init_debug_pre() because
the debug message can only print after uart is initialized. On the other hand,
multiboot cmdline need to be parsed before init_debug_pre() because the cmdline
could override uart settings and make sure debug message printed successfully.
This cause multiboot info was parsed in two stages.
The patch revise the multiboot parse logic that split sanitize_multiboot_info()
api and use init_acrn_multiboot_info() api for the early stage. The most of
multiboot info will be initialized during this stage and no debug message need
to be printed. After uart is initialized, the sanitize_multiboot_info() would
do sanitize multiboot info and print needed debug messages.
