HV: pci-vuart: pci based vuart emulation

Browse Source 
Add emulation for pci based vuart device mcs9900 at hv land.
add struct pci_vdev_ops vuart_pci_ops, the vdev callbalks for vuart.

How to use
In misc/vm_configs/scenarios/<SCENARIO>/<BOARD>/pci_dev.c, add pci
vuart config to vm_pci_devs[] array. For example:

struct acrn_vm_pci_dev_config vm0_pci_devs[] = {
       /* console vuart setting*/
       {
               .emu_type = PCI_DEV_TYPE_HVEMUL,
               .vbdf.bits = {.b = 0x00U, .d = 0x04U, .f = 0x00U},
               .vdev_ops = &vmcs_ops,
               .vbar_base[0] = 0x80001000,	/* mmio bar */
               .vbar_base[1] = 0x80002000,	/* msix bar */
               .vuart_idx = 0,
       },
       /* communication vuart setting */
       {
               .emu_type = PCI_DEV_TYPE_HVEMUL,
               .vbdf.bits = {.b = 0x00U, .d = 0x05U, .f = 0x00U},
               .vdev_ops = &vmcs_ops,
               .vbar_base[0] = 0x80003000,
               .vbar_base[1] = 0x80004000,
               .vuart_idx = 1,
               .t_vuart.vm_id = 1U,
               .t_vuart.vuart_id = 1U,
       },
}
