spi: Header and core clean up and refactoring

Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:

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.
