iommu/amd: Rename struct amd_io_pgtable iopt to pgtbl

Browse Source 
There is struct protection_domain iopt and struct amd_io_pgtable iopt.
Next patches are going to want to write domain.iopt.iopt.xx which is quite
unnatural to read.

Give one of them a different name, amd_io_pgtable has fewer references so
call it pgtbl, to match pgtbl_cfg, instead.
