it to correctly calculate the ACRN binary's load size if load_end_addr is
a non-zero value.
- multiboot2 can be enabled if hypervisor relocation is disabled.
- print the name of the boot loader. This might be helpful if the boot
loader, e.g. GRUB, inludes its version in the name string.

GRUB multiboot2 doesn't support relocation for ELF, which means it can't
load acrn.32.out to other address other than the one specified in ELF
header. Thus we need to use the raw binary file acrn.bin, and add
address/entry address/relocatable tags to instruct multiboot2 loader
how to load the raw binary.

BVT (Borrowed virtual time) scheduler is used to schedule vCPUs on pCPU.
It has the concept of virtual time, vCPU with earliset virtual time is
dispatched first.
Main concepts:
tick timer:
a period tick is used to measure the physcial time in units of MCU
(minimum charing unit).
runqueue:
thread in the runqueue is ordered by virtual time.
weight:
each thread receives a share of the pCPU in proportion to its
weight.
context switch allowance:
the physcial time by which the current thread is allowed to advance
beyond the next runnable thread.
warp:
a thread with warp enabled will have a change to minus a value (Wi)
from virtual time to achieve higher priority.
virtual time:
AVT: actual virtual time, advance in proportional to weight.
EVT: effective virtual time.
EVT <- AVT - ( warp ? Wi : 0 )
SVT: scheduler virtual time, the minimum AVT in the runqueue.

In platforms that support CAT, when it is enabled by ACRN, i.e.
IA32_resourceType_MASK_n registers are programmed with customized values,
it has impacts to the whole system.
The per guest flag GUEST_FLAG_CLOS_REQUIRED suggests that CAT may be
enabled in some guests, but not in others who don't have this flag,
which is conceptually incorrect.
This patch removes GUEST_FLAG_CLOS_REQUIRED, and adds a new Kconfig
entry CAT_ENABLED for CAT enabling. When it's enabled, platform_clos_array[]
defines a set of system-wide Class of Service (COS, or CLOS), and the
per guest vm_configs[].clos associates the guest with particular CLOS.

In current design, devicemodel passes VM UUID to create VMs and hypervisor
would check the UUID whether it is matched with the one in VM configurations.
Kata container would maintain few UUIDs to let ACRN launch the VM, so
hypervisor need to add these UUIDs in VM configurations for Kata running.
In the hypercall of hcall_get_platform_info(), hypervisor will report the
maximum Kata container number it will support. The patch will add a Kconfig
to indicate the maximum Kata container number that SOS could support.
In current stage, only one Kata container is supported by SOS on SDC scenario
so add one UUID for Kata container in SDC VM configuration. If we want to
support Kata on other scenarios in the future, we could follow the example
