Compiling with clang-16:

  drivers/acpi/acpi_lpit.c:142:6: error: no previous prototype \
  for function 'acpi_init_lpit' [-Werror,-Wmissing-prototypes]

  drivers/acpi/ioapic.c:212:6: error: no previous prototype \
  for function 'pci_ioapic_remove' [-Werror,-Wmissing-prototypes]

  drivers/acpi/ioapic.c:229:5: error: no previous prototype \
  for function 'acpi_ioapic_remove' [-Werror,-Wmissing-prototypes]

Include "internal.h" to silence them.
