patch for est patch for missing cpu

[Tom Hummel]

this patch adds support for Pentium 710 which isn't included in fbsd est
because this cpu isn't mentioned in the Intel docs.
However my lap has one.
The voltages this patch uses are those, which the msr of the cpu allows and
which the Pentium 715A uses, it works fine and seems to be correct,
however since these numbers are not official, I can't guarantee anything.
