expect config tool to calculate a correct MAX_MSIX_TABLE_NUM for hypervisor

number without evaluating the maximum MSI vectors that ACRN needed for vMSIX
emulation, thus introduce big risk on the device vMSIX table initialization.
If customer has special device that need larger MAX_MSIX_TABLE_NUM to enable

We need to deny accesses from SOS to the HV owned UART device, otherwise
SOS could have direct access to this physical device and mess up the HV
console.
If ACRN debug UART is configured as PIO based, For example,
CONFIG_SERIAL_PIO_BASE is generated from acrn-config tool, or the UART
config is overwritten by hypervisor parameter "uart=port@<port address>",
it could run into problem if ACRN doesn't emulate this UART PIO port
to SOS. For example:
- none of the ACRN emulated vUART devices has same PIO port with the
port of the debug UART device.
- ACRN emulates PCI vUART for SOS (configure "console_vuart" with
PCI_VUART in the scenario configuration)
This patch fixes the above issue by masking PIO accesses from SOS.
deny_hv_owned_devices() is moved after setup_io_bitmap() where
vm->arch_vm.io_bitmap is initialized.
Commit 50d852561 ("HV: deny HV owned PCI bar access from SOS") handles
the case that ACRN debug UART is configured as a PCI device. e.g.,
hypervisor parameter "uart=bdf@<BDF value>" is appended.
If the hypervisor debug UART is MMIO based, need to configured it as
a PCI type device, so that it can be hidden from SOS.

When hypervisor boots, the multiboot modules are loaded by bootloader(GRUB)
from HPA 0x100000 in order. The space range of pre-launched VM modules is also
exposed to SOS VM, so SOS VM kernel might pick this range to extract kernel
when KASLR enabled. This would corrupt pre-launched VM modules and result in
pre-launched VM boot fail.
This patch will try to fix this issue. The SOS VM will not be loaded to guest
space until all pre-launched VMs are loaded successfully.

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 higher address
after hypervisor and all multiboot modules to avoid guest
memory copy corruption;
2. For pre-launched VM, the kernel would be loaded to pref_address
first. If kernel end address is higher than maximum ramdisk
address limit, hypervisor would try to locate ramdisk load
address from 0x100000 to kernel load address; If kernel end
address is lower than maximum ramdisk address limit, hypervisor
would try to locate ramdisk address from kernel end address
to the maximum ramdisk address limit under 4GB;

The SOS VM should not use host efi memmap directly, since there are some
memory ranges which reserved by hypersior and pre-launched VM should not
be exposed to SOS VM. These memory ranges should be filtered from SOS VM
efi memmap, otherwise it would caused unexpected issues. For example, The
SOS kernel kaslr will try to find the random address for extracted kernel
image in EFI table first. So it's possible that these reserved memory is
picked for extracted kernel image. This will make SOS kernel boot fail.
The patch would create efi memmory map for SOS VM and pass the memory map
info to zeropage for loading SOS VM kernel. The boot service related region
in host efi memmap is also kept for SOS VM so that SOS VM could have full
capability of EFI services as host.

BTW, There should be a EBDA(Entended BIOS DATA Area) with reserved type
