We define attr.name in struct vm and named as ("vm_%d", attr.id). attr.name only
be used in debug tool vm_list. It does't deserve to do so in OS created flow
(aka function create_vm). It's better to handle this in vm_list tool.

Emulate VM0 resume from S3 state:
- reset BSP of VM0
- set the BSP entry to saved VM0 wakeup vec and set BSP to real mode
- start BSP
To match trampoline_spinlock release on ACRN Sx resume path, acquire
trampoline_spinlock if ACRN Sx enter fails.

MISRA C required that return value should be used, missing for it should
add "(void)" prefix before the function call.
Some function can be declared without return value to avoid this problem.

When we create an UOS, we didn't indicate the vmid.
Thus we can't get the vm description for the vm
description array.
Instead we use a temporary vm description to save data to
fill the vm structure when crate an UOS. It's uselesss once
UOS has created. So we don't need to maintain vm description
array here for UOS.

allocated all pcpus to vm0 to handle possible AP wakeup flow for all cpus,
as we pass org ACPI table to VM0 - that means VM0 can see all CPUs.
SOS(VM0) start expected CPUs through "maxcpus=" kernel cmdline option.
During first hypercall from SOS, calling vm_fixup to free un-expect-enabled
vcpus from VM0.

This address maybe invalid if a hostile address was set
in hypercall 'HC_SET_IOREQ_BUFFER'.it should be validated
before using.
Update:
-- save HVA to guest OS's request buffer in hyperviosr
-- change type of 'req_buf' from 'uint64_t' to 'void *'
-- remove HPA to HVA translation code when using this addr.
-- use error number instead of -1 when return error cases.

Before this patch, guest temporary page tables were generated by hardcode
at compile time, HV will copy this page tables to guest before guest
launch.
This patch creates temporary page tables at runtime for the range of 0~4G,
and create page tables to cover new range(511G~511G+16M) with trusty
requirement.
