Modified Files:
	src/sys/arch/i386/i386: est.c identcpu.c
	src/sys/arch/i386/include: cpu.h
	src/sys/arch/x86/include: specialreg.h

Log Message:
Update the enhanced speedstep driver and sync the code with OpenBSD:

est.c:

* Use a quintuplet (vendor, MHz_hi, mV_hi, MHz_lo, mV_lo } to match
  CPUs more correctly than parsing the brand string.
* Add support for a bunch of models.
* Create a fake table on the fly if the CPU is unknown (there's no
  table for it) with the current/highest/lowest frequency.

specialreg.h:

* Add some MSRs needed to get the bus clock value.

identcpu.c:

* Add functions specific to Pentium III, Pentium M and Pentium 4 to
  get the bus clock value.

Note that the new fake table code from Simon Burge is not included on
this commit.
