In pre-launched VM the GPA of vmsix BAR which is used for vmsix
over msi is calculated/allocated by acrn-config tool. The GPA
needs to be assigned to vdev when vdev is initialized. The
assignment is only needed for pre-launched VM. For SOS kernel
will reprogram the Bar base when startup. For post-launched VM
the Bar GPA will be assigned by device model via hypercall.

When init_vmsix_on_msi is called during the initialization of a pt
device, the vmsix bar used for vmsix over msi is just created. No
mapping/unmapping is done and pci_vdev_write_vbar should be called
instead of vdev_pt_write_vbar at the time. Currently the Bar mapping
is delayed till OS sizing the Bar. Backup vbar base_gpa to mmio_gpa
is not required here becuase it will be done later when Bar mapping.

pm_vuart stops listening and relays the message right away if it

Add functionality to get free vbar base for the vmsix devices.
- The devices size is 4k.
- The mmio range for non SOS VM is 2G to 4G
- The mmio range for SOS is depended on the range which is assigned to
PCI bus hostbridge
- The next vbar index is based on last device vbar index vbar_i

vmsix.c originally covers ptdev case but ACRN hypervisor
need to support pure virtual PCI mediator, such as ivshmem
device in this patch set.
For better understanding the code changes from patch
perspective, split the changes to several small patches.
This patch moves most original vmsix code to pci_pt.c
as they're mixed with ptdev specific operations.
The subsequent patches will start the detail abstraction change.

Now ACRN supports direct boot mode, which could be SBL/ABL, or GRUB boot.
Thus the vboot wrapper layer can be removed and the direct boot functions
don't need to be wrapped in direct_boot.c:
- remove call to init_vboot(), and call e820_alloc_memory() directly at the
time when the trampoline buffer is actually needed.
- Similarly, call CPU_IRQ_ENABLE() instead of the wrapper init_vboot_irq().
- remove get_ap_trampoline_buf(), since the existing function
get_trampoline_start16_paddr() returns the exact same value.
- merge init_general_vm_boot_info() into init_vm_boot_info().
- remove vm_sw_loader pointer, and call direct_boot_sw_loader() directly.
- move get_rsdp_ptr() from vboot_wrapper.c to multiboot.c, and remove the
wrapper over two boot modes.

Since now we support direct boot only, we don't have to use FIRMWARE variable
to differentiate between sbl/GRUB and UEFI boot.
After this change:
- "FIRMWARE=sbl/uefi" should be removed from make commands.
- the firmware name is removed from the installed ACRN image. For example,
acrn.apl-up2.sbl.sdc.32.out will be changed to acrn.apl-up2.sdc.32.out.
