turbostat already checks whether calling each cpuid leavf is legal,
and it doesn't look at the function return value,
so call the simpler gcc intrinsic __cpuid() instead of __get_cpuid().

The accuracy of Bzy_Mhz and Busy% depend on reading
the TSC, APERF, and MPERF close together in time.

When there is a very short measurement interval,
or a large system is profoundly idle, the changes
in APERF and MPERF may be very small.
They can be small enough that an expensive interrupt
between reading APERF and MPERF can cause the APERF/MPERF
ratio to become inaccurate, resulting in invalid
calculation and display of Bzy_MHz.

A dummy APERF read of APERF makes this problem
much more rare.  Apparently this 1st systemn call
after exiting a long stretch of idle is when we
typically see expensive timer interrupts that cause
large jitter.

For the cases that dummy APERF read fails to prevent,
we compare the latency of the APERF and MPERF reads.
If they differ by more than 2x, we re-issue them.

The column "GFX%c6" show the percentage of time the GPU
is in the "render C6" state, rc6.  Deep package C-states on several
systems depend on the GPU being in RC6.

This information comes from the counter
/sys/class/drm/card0/power/rc6_residency_ms,
as read before and after the measurement interval.

Under the column "GFXMHz", show a snapshot of this attribute:

This is an instantaneous snapshot of what sysfs presents
at the end of the measurement interval.  turbostat does
not average or otherwise perform any math on this value.

The new IRQ column shows how many interrupts have occurred on each CPU
during the measurement inteval.  This information comes from
the difference between /proc/interrupts shapshots made before
and after the measurement interval.

The first row, the system summary, shows the sum of the IRQS
for all CPUs during that interval.

Following changes have been made:
- changed MSR_NHM_TURBO_RATIO_LIMIT to MSR_TURBO_RATIO_LIMIT in debug print
  for consistency with Developer Manual
- updated definition of bitfields in MSR_TURBO_RATIO_LIMIT and appropriate
  parsing code
- added x200 to list of architectures that do not support Nahlem compatible
  definition of MSR_TURBO_RATIO_LIMIT register (x200 has the register but
  bits definition is custom)
- fixed typo in code that parses MSR_TURBO_RATIO_LIMIT
  (logical instead of bitwise operator)
- changed MSR_TURBO_RATIO_LIMIT parsing algorithm so the print out had the

x200 does not enable any way to programmatically obtain bus clock
speed. Bclk for the architecture has a fixed value of 100 MHz.
At the same time x200 cannot be included in has_snb_msrs since
it does not support C7 idle state.

prior to this patch, MHz values reported on this chip
were erroneously calculated using bclk of 133MHz,
causing MHz values to be reported 33% higher than actual.
