Commit 004172bdad64432 (sched/core: Remove unnecessary #include
headers) removed the inclusion of asm/paravirt.h which is used to get
declarations of paravirt_steal_rq_enabled and paravirt_steal_clock.  It
is implicitly included on but not on arm and arm64 breaking the build if
paravirtualization is used.  Since things from that header are used
directly fix the build by putting the direct inclusion back.
