Subject: [PATCH] iommu/renesas: fix unused-function warning

gcc warns because the only reference to ipmmu_find_group
is inside of an #ifdef:

drivers/iommu/ipmmu-vmsa.c:878:28: error: 'ipmmu_find_group' defined but not used [-Werror=unused-function]

Change the #ifdef to an equivalent IS_ENABLED().

Fixes: 6580c8a78424 ("iommu/renesas: Convert to probe/release_device() call-backs")
