Add new OA formats for DG2. Some of the newer OA formats are not
multples of 64 bytes and are not powers of 2. For those formats, adjust
hw_tail accordingly when checking for new reports.
v2:
- Update commit title (Ashutosh)
- Coding style fixes (Lionel)
- 64 bit OA formats need UMD changes in GPUvis, drop for now and send in a
separate series with UMD changes
