[PATCH] x86: don't include processor.h from system.h

[Jan Beulich <jbeulich@xxxxxxxx>]

processor.h in particular pulls in xen/smp.h, which is overly heavy for
a supposedly pretty fundamental header like system.h. To keep things
building, move the declarations of struct cpuinfo_x86 and boot_cpu_data
to asm/cpufeature.h (which arguably also is where they belong). In the
course of the move switch away from using fixed-width types and convert
plain "int" to "unsigned int" for the two x86_cache_* fields.
