iommu/ipmmu-vmsa: Remove ipmmu_utlb_disable()

Browse source 
The function is unused after commit 1b932ceddd ("iommu:
Remove detach_dev callbacks") and so compilation fails with

drivers/iommu/ipmmu-vmsa.c:305:13: error: ‘ipmmu_utlb_disable’ defined but not used [-Werror=unused-function]
  305 | static void ipmmu_utlb_disable(struct ipmmu_vmsa_domain *domain,
      |             ^~~~~~~~~~~~~~~~~~

Remove the function to fix the compile error.
