[patch V3 16/60] x86/xen/pv: Pretend that it found SMP configuration

From: Thomas Gleixner
Date: Tue Aug 01 2023 - 06:48:15 EST


Unlike all other SMP configuration "parsers" XEN/PV does not set
smp_found_config which is inconsistent and prevents doing proper decision
logic based on this flag.

Make XEN/PV pretend that it found SMP configuration.
