mshv: hide x86-specific functions on arm64 



The hv_sleep_notifiers_register() and hv_machine_power_off() functions are
only called and declared on x86, but cause a warning on arm64:

drivers/hv/mshv_common.c:210:6: error: no previous prototype for 'hv_sleep_notifiers_register' [-Werror=missing-prototypes]
  210 | void hv_sleep_notifiers_register(void)
      |      ^~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/hv/mshv_common.c:224:6: error: no previous prototype for 'hv_machine_power_off' [-Werror=missing-prototypes]
  224 | void hv_machine_power_off(void)
      |      ^~~~~~~~~~~~~~~~~~~~

Hide both inside of an #ifdef block.

Fixes: 615a6e7d ("mshv: Cleanly shutdown root partition with MSHV")
