x86: change aper valid checking sequence
old sequence:
size ==> >4G ==> point to RAM
changed to:
>4G ==> point to RAM ==> size
some bios even leave aper to unclear, so check size at last.
To avoid reporting:
Node 0: Aperture @ 4a42000000 size 32 MB
Aperture too small (32 MB)
with this change we will get:
Node 0: Aperture @ 4a42000000 size 32 MB
Aperture beyond 4G. Ignoring.
