iommu/amd: Refactor helper function for setting / clearing GCR3
Refactor GCR3 helper functions in preparation to use per device
GCR3 table.
* Add new function update_gcr3 to update per device GCR3 table
* Remove per domain default GCR3 setup during v2 page table allocation.
Subsequent patch will add support to setup default gcr3 while
attaching device to domain.
* Remove amd_iommu_domain_update() from V2 page table path as device
detach path will take care of updating the domain.
* Consolidate GCR3 table related code in one place so that its easy
to maintain.
* Rename functions to reflect its usage.
