HV: added memory allocation functions for AP trampoline code relocation

Browse Source 
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
