The current logic that returns (sys_addr >> 8) & 0x7 when
num_dcts_intlv = 4 is incorrect. We should really be doing-
If intlv_addr = 0x4, then interleave on bits [9:8] and if
intlv_addr = 0x5, interleave on bits [10:9].

Refer F15 M30h BKDG D18F2x110[7:6] (DRAM Controller Select Low)
(Link:http://support.amd.com/TechDocs/49125_15h_Models_30h-3Fh_BKDG.pdf)

Tested on F15 M30h with mce_inj module and patch did not cause
any regressions.
