[PATCH] i386/x86-64: Update AMD CPUID flags 

Print bits for RDTSCP, SVM, CR8-LEGACY.

Also now print power flags on i386 like x86-64 always did.
This will add a new line in the 386 cpuinfo, but that shouldn't
be an issue - did that in the past too and I haven't heard
of any breakage.

I shrunk some of the fields in the i386 cpuinfo_x86 to chars
to make up for the new int "x86_power" field. Overall it's
smaller than before.
