i945: Disable check for 2-dimm support.

The check is wrong. On Acer Aspire One it returns 0 despite 2 DIMMs working
    fine on the same channel if this check is disabled (tested by memtest).
    On boards that have only 1 DIMM per channel, the code will simply find no
    SPD and skip empty slot.
