Shuo A Liu 98c80d75b8 hv: dm: Use new virtual device management ioctls
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.

Tao Yuhong 996e8f680c HV: pci-vuart support create vdev hcall
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

Yuan Liu 6d0f0ebd8a hv: implement ivshmem device creation and destruction
For ivshmem vdev creation, the vdev vBDF, vBARs, shared memory region
name and size are set by device model. The shared memory name and size
must be same as the corresponding device configuration which is configured
by offline tool.

v3: add a comment to the vbar_base member of the acrn_vm_pci_dev_config
    structure that vbar_base is power-on default value

Yuan Liu 92f9f5a4f3 hv: add ivshmem device
Ivshmem device is used for shared memory based communication between
pre-launched/post-launched VMs.

this patch implements ivshmem device configuration space initialization
and ivshmem device operation methods.

v2: introduce init_one_pcibar interface to simplify BAR initialization
    operation of HV emulated PCI device.

v3: 1) due to init_one_pcibar API is only used for pre-launched VM vdevs
       it can't be applied to all vdevs, so remove it.
    2) move ivshmem BARs initialization to subsequent patch, this patch
       only introduce ivshmem configuration space initialization.

Yuan Liu d6f563c4eb hv: implement ivshmem memory regions initialization
The ivshmem memory regions use the memory of the hypervisor and
they are continuous and page aligned.

this patch is used to initialize each memory region hpa.

v2: 1) if CONFIG_IVSHMEM_SHARED_MEMORY_ENABLED is not defined, the
       entire code of ivshmem will not be compiled.
    2) change ivshmem shared memory unit from byte to page to avoid
       misconfiguration.
    3) add ivshmem configuration and vm configuration references

v3: 1) change CONFIG_IVSHMEM_SHARED_MEMORY_ENABLED to CONFIG_IVSHMEM_ENABLED
    2) remove the ivshmem configuration sample, offline tool provides default
       ivshmem configuration.
    3) refine code style.

v4: 1) make ivshmem_base 2M aligned.
