[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) Signed-off-by: Sebastian Witt <se.witt@gmx.net> Signed-off-by: Dave Jones <davej@redhat.com>
