Introduce a weak function to let the platform code provide the processor
voltage in 100mV units.
Implement the function on Intel platforms using the MSR_PERF_STATUS msr.
On other platforms the processor voltage still reads as unknown.
Tested on Intel CFL. The CPU voltage is correctly advertised.

msr_set_bit can only set single bits in MSRs and causes mixing of bit
positions and bitmasks in the MSR header files. Thus, replace the helper
by versions which can unset and set whole MSR bitmasks, just like the
"and-or"-helper, but in the way commit 64a6b6c was done (inversion done
in the helper). This helps keeping the MSR macros unified in bitmask
style.
In sum, the three helpers msr_set, msr_unset and msr_unset_and_set get
added.
The few uses of msr_set_bit have been replaced by the new version, while
the used macros have been converted accordingly.

Current implementation uses CPUID 0Bh function that returns the number
of logical cores of requested level. The problem with this approach is
that this value doesn't change when HyperThreading is disabled (it's in
the Intel docs), so it breaks generate_cpu_entries().
- Use MSR 0x35 instead, which returns the correct number of logical
processors with and without HT.
- Rename the function to get_logical_cores_per_package, which is more
accurate.
Tested on ThinkPad X220 with and without HT.

This is required for Super I/Os to be able to read the CPU temperature
through PECI.
On 45nm Core 2 CPUs (Wolfdale, Yorkfield) it is not enabled by default.
This is probably related to erratum AW67 "Enabling PECI via the PECI_CTL
MSR incorrectly writes CPUID_FEATURE_MASK1 MSR". The suggested
workaround is "Do not initialize PECI before processor update is
loaded". Since coreboot performs microcode updates before running this
code it should not cause any trouble. It was tested on a Core 2 Duo
E8400, stepping E0.
PECI is already enabled by default on older (65nm) CPUs. Tested: Pentium
Dual-Core E2160.
