Hannes Eder 4e42ebd57b x86: hypervisor - fix sparse warnings
Impact: fix sparse build warning

Fix the following sparse warnings:

  arch/x86/kernel/cpu/hypervisor.c:37:15: warning: symbol
  'get_hypervisor_tsc_freq' was not declared. Should it be static?
  arch/x86/kernel/cpu/hypervisor.c:53:16: warning: symbol
  'init_hypervisor' was not declared. Should it be static?
