iommu/amd: Refactor GCR3 table helper functions

Browse source

To use the new per-device struct gcr3_tbl_info. Use GFP_KERNEL flag
instead of GFP_ATOMIC for GCR3 table allocation. Also modify
set_dte_entry() to use new per device GCR3 table.

Also in free_gcr3_table() path replace BUG_ON with WARN_ON_ONCE().
