- commit 69152647 ("hv: Use virtual APIC IDs for Pre-launched VMs")
enables virtual APIC IDs for pre-launched VMs thus xapic_phys is no
longer needed to force guest xAPIC to work in physical destination mode.
- HVC is not available in logical partition mode and "console=hvc0" should
be removed from guest Linux bootargs.

Add this vcpu_affinity[] for each VM to indicate the assignment policy.
With it, pcpu_bitmap is not needed, so remove it from vm_config.
Instead, vcpu_affinity is a must for each VM.
This patch also add some sanitize check of vcpu_affinity[]. Here are
some rules:
1) only one bit can be set for each vcpu_affinity of vcpu.
2) two vcpus in same VM cannot be set with same vcpu_affinity.
3) vcpu_affinity cannot be set to the pcpu which used by pre-launched VM.
v4: config SDC with CONFIG_MAX_KATA_VM_NUM
v5: config SDC with CONFIG_MAX_PCPU_NUM

There is plan that define each VM configuration statically in HV and let
DM just do VM creating and destroying. So DM need get vcpu_num
information when VM creating.
This patch return the vcpu_num via the API param. And also initial the
VMs' cpu_num for existing scenarios.

Previously multiboot mods[0] is designed for kernel module for all
pre-launched VMs including SOS VM, and mods[0].mm_string is used
to store kernel cmdline. This design could not satisfy the requirement
of hybrid mode scenarios that each VM might use their own kernel image
also ramdisk image. To resolve this problem, we will use a tag in
mods mm_string field to specify the module type. If the tag could
be matched with os_config of VM configurations, the corresponding
module would be loaded;

In previous code, only for pre-launched VM, hypervisor would create
vuart console for each VM. But for post-launched VM, no vuart is
created.
In this patch, create vuart according to configuration in structure
acrn_vm_config. As the new configuration is set for pre-launched VM and
post-launched VM, and the vuart initialize process is common for each
VM, so, remove CONFIG_PARTITION_MODE from vuart related code.
