[CPUFREQ] Samuel2 can use eblcr to determine FSB.

From: Sven Traenkle.

here's a patch that solves some issues I have with the longhaul cpufreq
driver on my epia 6000CL/Via EDEN (actually reporting as CentaurHauls,
family 6, model 7, VIA Samuel 2). The driver tries to compute the fsb speed
while it could actually use the fixed values (as it does for model == 6).
I got this change from the via forum, so no credits to me.
