It modifies the signature of init_iommu_domain
in order to remove dependency on acrn_vm from
inside vtd.c.
Incorporated comments from Jason and Eddie.

Using term of VM0 would mislead to a VM with VM id 0 easily, whereas
VM id 0 could be used for any PRE_LAUNCHED_VM. So replace VM0 with
SOS_VM.

This is the following patch after removing pending_pre_work, it make sure
all io emulation is done on its own cpu.
For hv emulated request, it follows the steps:
hv_emulate_pio->emulate_pio_complete
hv_emulate_mmio->emulate_mmio_complete
For dm emulated request, it follows the steps:
acrn_insert_request->dm_emulate_io_complete
while in acrn_insert_request, it could trigger scheduling out then resume by
hcall_notify_ioreq_finish, or busy wait for ioreq completion if polling mode
is enabled.

Under sharing mode, VM0 is identical with SOS VM. But the coupling of
SOS VM and VM 0 is not friendly for partition mode.
This patch is a pure term change of vm0 to sos VM, it does not change

ACRN hypervisor follows MISRA-C which has some inconsistencies with the Linux
kernel coding style. Namely,
* Braces are required even for single-statement blocks.
* Zero-initialisers to global variables are allowed.
* Line limit is 120 instead of 80.
This patch adds a .checkpatch.conf so that checkpatch.pl stops warning on the
exceptions above when invoked under the root directory of the acrn-hypervisor
repository.
