RTVM (with lapic PT) boots hang when maxcpus is
assigned a value less than the CPU number configured
in hypervisor.
In this case, vlapic_state(per VM) is left in TRANSITION
state after BSP boot, which blocks interupts to be injected
to this UOS.

There's no need to look up MSI ptirq entry by virtual SID any more since the MSI
ptirq entry would be removed before the device is assigned to a VM.
Now the logic of MSI interrupt remap could simplify as:
1. Add the MSI interrupt remap first;
2. If step is already done, just do the remap part.

it from the (current) user, then give it back to its parent user.
When we deassign the vdev from the (current) user, we would de-initialize the
vMSI/VMSI-X remapping, so does the vMSI/vMSI-X data structure.

If HV relocation is enabled, either ACRN efi-stub or GRUB relocates
hypervisor image above HPA 256MB, thus we put hvlog and ramoops buffer
under 256MB to avoid conflict with hypervisor owned address.
This patch hardcodes these addresses:
0xa00000 - 0xdfffff: 4MiB for ramoops buffer
0xe00000 - 0xffffff: 2MiB for hvlog buffer
However, user can customize them to other addresses as long as it's under
256MB, available in host e820, and SOS bootarg "nokaslr" is not specified.
If HV relocation is disabled, need to make sure that these buffer
addresses are not between HV_RAM_START and HV_RAM_START + HV_RAM_SIZE.

For post-launched VMs, the configured CPU affinity could be different
from the actual running CPU affinity. This new field acrn_vm->cpu_affinity
recognizes this difference so that it's possible that CREATE_VM
hypercall won't overwrite the configured CPU afifnity.
Change name cpu_affinity_bitmap in acrn_vm_config to cpu_affinity.
This is read-only in run time, never overwritten by acrn-dm.
Remove vm_config->vcpu_num, which means the number of vCPUs of the
configured CPU affinity. This is not to be confused with the actual
running vCPU number: vm->hw.created_vcpus.
Changed get_vm_bsp_pcpu_id() to get_configured_bsp_pcpu_id() for less
