Various cleanups and refactorings of the SPI header and core parts
united in a single series. It also touches drivers under SPI subsystem
folder on the pure renaming purposes of some constants.

No functional change intended (with some subtle shortcuts which are
explained in the respective commit messages).

Changelog v3:
- dropped controversial used to be patches 3,4,8,10 (Mark)
- amended many commit messages (Mark)
