The vuart_read()/vuart_write() are coupled with PIO vuart type. Move
the non-type related code into vuart_read_reg()/vuart_write_reg(), so
that we can re-use them to handle MMIO request of pci-vuart type.

We don't reserve PCI MMIO in e820 Table, it's included in DSDT ACPI Table.
About 0xA0000 - 0x100000 entry, we don't have any ACPI Table touch this region.
So we could remove it too.
After this change, we could only pass the reserved e820 table which we must
reserve to OVMF. In this case, the OVMF could trust ACRN-DM and pass the
reserved e820 table to guest instead of dropping it.
This patch needs the corresponding modify in OVMF. Otherwise, the guest could
not boot.

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.

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.

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.
