There are two things here:
1. Enable basic vsbl boot functionality.
2. add long option to DM to specific vsbl file. So DM could
choice to boot guest with vsbl.
It's hard to find a suitable short option. So only long option
is supported for vsbl file name option.
If long option "--vsbl='vsbl_file_name'" is given in DM
commandline, the "vsbl_file_name" will be loaded by DM
first and running. vsbl will be response to lead guest to
next boot stage.

Will update e820 table to mark the address ACPI specific type.
Also need pass ACPI table start address and size to vsbl.

gcc8 showed following errors when build DM:
error: argument to ‘sizeof’ in ‘strncpy’ call is the same
expression as the source; did you mean to use the size of the
destination? [-Werror=sizeof-pointer-memaccess]
It looks like wrong parameter was given to strncpy.

New compiler options introduced by commit
519c4285cf will cause DM compile failure
which caused by warnings from some snprintf usage might be truncated.

Some virtio PCI devices can change the device configuration state, as
reflected in the device-specific configuration region of the device. In
this case:
* If MSI-X capability is disabled:
1. Set the second lower bit of the ISR Status field for the device
2. Send the appropriate PCI interrupt for the device.
* If MSI-X capability is enabled:
1. If config_msix_vector is not NO_VECTOR, request the appropriate
MSI-X interrupt message for the device, config_msix_vector sets
the MSI-X Table entry number.
A single interrupt MAY indicate both that one or more virtqueue has been
used and that the configuration space has changed.

IPU devices are using I2C device with physical BDF 0:16.0.
The I2C controller has the dependency on ACPI info.
This patch is to add ACPI info for the I2C controller and the two IPU
devices that are under the scope of I2C.
Note:
This patch is specific for GP platform.

Linux kernel CF9 reboot is doing things like:
- read value from 0xcf9
- mask out the value according to the reboot type (warm vs cold)
- BIT OR the value with reboot code
- write the value to 0xcf9
If there are two reboot event and the first one is cold
reboot and the second one is warm reboot, vsbl query
reboot type after the second one and will get code reboot
instead of warm reboot.
We should clear the data of 0xcf9 if guest request cold reboot.

instead of warm reboot.
So we set 0xE to reset value of FADT to make ACPI reboot

RELRO rearranges the data sections inside an ELF
