[PATCH 1/5] x86/build: Rework includes in genapic/probe.c

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

probe.c includes a large number of headers which are unused, and not from
churn so far as I can see in history.  Strip back to a reasonable set.

One complication is that genapic.h has to include xen/cpumask.h because
there's no way to forward declare a cpumask_t.

Also strip trailing whitespace while adjusting the file.
