[PATCH v1 6/8] spi: Clean up headers

[Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>]

There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically
