[CPUFREQ] sets nforce2 minimum PLL divider to 2. 



Sets minimum PLL divider to 2.
No negative impact when tested with two nForce2 based boards.

Alexander Choporov reported (06/01/06) that xdiv = 1 does not work on his
Abit NF7S2. Although there shouldn't be much cases that lead to xdiv = 1.

(Updates also the (C) year)
