[PATCH v2 00/10] Tidy some minor things in the stream table/cd table area

[Jason Gunthorpe]

Will pointed out that two places referring to the CD/STE struct did not
get the new types. While auditing this code a few more oddities were
noticed. Based on a feedback from Mostafa and Nicolin a few more things
were fixed up too

- Use types for all the HW structures everywhere even for the L1
  descriptors that are just a single 8 bytes. This helps with clarity of
  what everthing is pointing at
- Use indexing helpers for the STE/CD two level calculations
- Use sizeof(struct X) instead of open coded math on constants. The sizeof
  naturally follows the type of the related variable in almost all cases
- Remove redundant dma_addr_t's and save some memory
- Remove redundant devm usage
- Use the modern rbtree API

Parts of this have been sitting in my tree for a while now, it grew a bit
since v1, but nothing is particularly profound here. Enough is merged now
that they can be cleanly based and are seperate from my other series.

v2:
 - Add a patch to add structs for the L1/L2 HW layouts and use their
   sizeof and type instead of constants and generic __le64 *.
 - Add a patch for L1/L2 indexing helpers for clarity
 - Reorder patches
 - Redo the union layout in the cfg for both cases
 - Fully remove some more defines
