[PATCH v2 00/15] spi: Header and core clean up and refactoring

[Andy Shevchenko]

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.

Changelog v2:
- added new patches 3,4,5,10,13,14
- massaged comment and kernel doc in patch 9
- split used to be patch 4 to patches 11,12
- covered a few things in SPI core in patch 15
- amended commit message for above (Mark)
- reshuffled patches in the series for better logical grouping
