These are cleanups against 2098142ae87d, the current pci/host-rockchip
head in my tree.
Changes from v1:
- Rework HIWORD_UPDATE
- Remove duplicate CSR definitions
- Move CSR block offset from read/write caller to CSR definition
- Organize CSRs into logical blocks
- Fix some inconsistent CSR names
- Add names for registers at the base of CSR blocks
I was disappointed to find how disorganized the v10 CSR definitions were.
It was quite a hodgepodge. I should have noticed that earlier, but as
penance, I tried to clean it up myself.
These are in git as pci/host-rockchip-wip. Again, I intend to squash these
all into the single commit that adds the driver when I finally merge it.
