Pull up following revision(s) (requested by jakllsch in ticket #257):

        sys/stand/efiboot/efiblock.c: revision 1.7

Use roundup2() instead of open coding something almost the same that
truncates 64-bit quantities.

Fixes disk access and booting in bootaa64.efi on SoftIron OverDrive 1000
(which does not have any memory below 4GiB).
