* bad DQs).

* This HWP should be called by HWP/PLAT code to access the BAD DQ Bitmap
*
* Note that the MSB of each byte corresponds to the lowest DQ.
* if (data[1][0] == 0x80) then rank 1, Centaur DQ0 is bad
* if (data[1][0] == 0x40) then rank 1, Centaur DQ1 is bad
* if (data[1][1] == 0x20) then rank 1, Centaur DQ10 is bad
