ceb3076b69 HV: added memory allocation functions for AP trampoline code relocation
V2->V3: Fixed the booting issue on MRB board and removed the restriction
        of allocate memory from address 0

1) Fix the booting from MRB issue
-#define    CONFIG_LOW_RAM_SIZE 0x000CF000
+#define    CONFIG_LOW_RAM_SIZE 0x00010000

2) changed e820_alloc_low_memory() to handle corner case of unaligned e820 entries
  and enable it to allocate memory at address 0
+		a length = end > start ? (end - start) : 0;

-       /* We don't want the first page */
-       if ((length == size) && (start == 0))
-           continue;

3) changed emalloc_for_low_mem() to enable to allocate memory at address 0
-       /* We don't want the first page */
-       if (start == 0)
-           start = EFI_PAGE_SIZE;

V1->V2: moved e820_alloc_low_memory() to guest.c and added the logic to
        handle unaligned E820 entries

emalloc_for_low_mem() is used if CONFIG_EFI_STUB is defined.
e820_alloc_low_memory() is used for other cases

In either case, the allocated memory will be marked with E820_TYPE_RESERVED

9323f811ea HV: Prepare cpu_secondary.S for AP trampoline code relocation
V1->V2: removed CONFIG_LOW_RAM_START and added ".org 0" to
cpu_secondary.S

The assumption is trampoline code is relocated while HV is not, so:

trampoline code is built at address 0, and CS register is updated
by SIPI to reflect the correct vector

in real mode part, added extra pointers for page tables and long jump buffer
so it's possible for HV code to patch the relocation offset

in long mode part, use absolute addressing when referring HV symbols,
and use relative addressing for symbols within trampoline code

c0d4b90415 ptdev: change remapping entry from virtual to physical based
currently, pass-thru devices are managed by per-vm's remapping entries
which is virtual based:
- MSI entry is identified by virt_bdf+msix_index
- INTx entry is identified by virt_pin+vpin_src
it works but it's not a good design for physical resource management, for
example a physical IOAPIC pin could belong to different vm's INTx entries,
the Device Model then must make sure there is no resource conflict from
application's level.

This patch change the design from virtual to physical based:
- MSI entry is identified by phys_bdf+msix_index
- INTx entry is identified by phys_pin
The physical resource is directly managed in hypervisor, a miss adding
entry will be found by hypervisor and return error message with failure.
