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.

- rename it to 'io_shared_page' to keep consistent
with ACRN HDL foils.
- update related code that reference this data structure.

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.

this patch is a preparation for changing ptdev remapping entry from
virtual to physical based, it changes the ptdev_lock from per-vm to
global, as entries based on physical mode are global resource.
