RAS/AMD/ATL: Include row[13] bit in row retirement

Based on feedback from hardware folks, row[13] is part of the variable
bits within a physical row (along with all column bits).

Only half the physical addresses affected by a row are calculated if
this bit is not included.

Add the row[13] bit to the row retirement flow.
