at91: move reset vector to board code

Hi all.

The following patchset moves the reset vector for at91 boards from mach-at91 to board code. This is similar to what other boards do and is done to prepare for multi-image and DT support.

The patchset includes removal of the mmccpu board.

The patchset convert all at91 boards and thus clean up the old code that resided in mach-at91/

The second patch have minimal impact, but prepares for a board-by-board conversion.
All temporary CONFIG symbols are gone at the end of this series.

I kept Jean-Christophe PLAGNIOL-VILLARD and others copyright in all the created files and did not add copyright myself. The patchset does IMO not add any copyrightable material from my side as this is in reality just moving around code.

With this patchset applied we no longer have any places where we call board code from mach-at91/ thus allowing us to introduce multi-images.
And we are also on the right track to introduce DT support for additional AT91 based boards.

The patchset was successfully booted on a AT91SAM9263EK, and all defconfigs was built (expect the ones that failed to build before this patchset was applied).

I consider the patchset ready for barebox-next.

Changes v4 => v5
Fix whitespace issues all over (Sascha) Include lowlevel_init for tny_a9263 (Sascha) Delete mmccpu and updated patchset (Sascha) Use proper versioning of patches (Andrey) Combined a few patches deleting code (Sam)

Changes v3 => v4
Updated at91sam926x_board_init.h based on feedback from Andrey Smirnov

Changes v2 => v3
v2 was posted in July - but I have lacked spare time until now to give it a proper respin
- respin of all patches on top of v2017.12.0
- fix bogus handling of at91sam926x_board_init
- Introduce new CONFIG symbol for at91sam926x_board_init to allow bisects

Changes v1 => v2
- converted all boards over
- fixed author info
