iommu: Remove functions that support private domain

Browse Source 
After moving iommu_group setup to iommu core code [1][2] and removing
private domain support in vt-d [3], there are no users for functions such
as iommu_request_dm_for_dev(), iommu_request_dma_domain_for_dev() and
request_default_domain_for_dev(). So, remove these functions.

[1] commit dce8d6964e ("iommu/amd: Convert to probe/release_device()
    call-backs")
[2] commit e5d1841f18 ("iommu/vt-d: Convert to probe/release_device()
    call-backs")
[3] commit 327d5b2fee ("iommu/vt-d: Allow 32bit devices to uses DMA
    domain")
