nb/intel/gm45: Fix raminit with mixed raw card types

`cardF[n]` should indicate whether the DIMM in channel n is of
raw card type F. However, `cardF[1]` was initialised with the
value meant for `cardF[0]`. This patch results in the correct
initialisation of `cardF`.

Tested on a Lenovo T400 containing two DIMMs: one of raw card
type F and the other of raw card type B. Before the patch, the
system would not boot. After the patch, the system boots with all
of the memory functional.
