IC_ADD_HV_VDEV -> ACRN_IOCTL_CREATE_VDEV
IC_REMOVE_HV_VDEV -> ACRN_IOCTL_DESTROY_VDEV
struct acrn_emul_dev -> struct acrn_vdev
Also, move struct acrn_vdev to acrn_common.h as this structure is used
by both DM and HV.

For a pci BAR, its size aligned bits have fixed to 0(except the memory
type bits, they have another fixed value), they are read-only.
When write ~0U to BAR for sizing, (type_bits | size_mask) is written
into BAR.
So do not need to distinguish between sizing vBAR and programming vBAR.
When write a value to vBAR, always store (value & size_mask | type_bit)
to vfcg.
pci_vdev_read_vbar() is unnecessary, because it is only need to read
vcfg.

Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".
In other words, we are adopting the same practice in Linux kernel.

When wrong BAR address is set for pci-vuart, OS may assign a
new BAR address to it. Pci-vuart BAR can't be reprogrammed,
for its wrong fixed value. That can may because pci_vbar.fixed and
pci_vbar.type has overlap in abstraction, pci_vbar.fixed
has a confusing name, pci_vbar.type has PCIBAR_MEM64HI which is not
really a type of pci BARs.
So replace pci_vbar.type with pci_vbar.is_mem64hi, and change
pci_vbar.fixed to an union type with new name pci_vbar.bar_type.

Add cteate method for vmcs9900 vdev in hypercalls.
The destroy method of ivshmem is also suitable for other emulated vdev,
move it into hcall_destroy_vdev() for all emulated vdevs

if vuart type is pci-vuart, then use MSI interrupt
split vuart_toggle_intr() control flow into vuart_trigger_level_intr() &
trigger_vmcs9900_msix(), because MSI is edge triggered, no deassertion
operation. Only trigger MSI for pci-vuart when assert interrupt.
