[PATCH 6/8] iommu/amd: fix a couple of spelling mistakes

[Zhen Lei <thunder.leizhen@huawei.com>]

There are several spelling mistakes, as follows:
alignement ==> alignment
programing ==> programming
implemtation ==> implementation
assignement ==> assignment

By the way, both "programing" and "programming" are acceptable, but the
latter seems more formal.
