Use a new CPU feature word to cover features that are spread around

Some Intel features are spread around in different CPUID leafs like 0x5,
0x6 and 0xA.  Make this feature detection code common across i386 and
x86_64.

Display Intel Dynamic Acceleration feature in /proc/cpuinfo. This feature
will be enabled automatically by current acpi-cpufreq driver.

Refer to Intel Software Developer's Manual for more details about the feature.

Thanks to hpa (H Peter Anvin) for the making the actual code detecting the
scattered features data-driven.
