Subject: [PATCH 1/5] at91: refactor lowlevel_init selection
Push selection of lowlevel_init functions out to the individual
boards.
Pushing it to the individual boards allows us on a per board basis
to migrate to a design where the mach-at91 code no longer
calls the board specific code.
When the dependency mach-at91 => boards is dropped for
a board the migration to a multi-image setup is one step closer.

After the refactoring of how we select lowlevel_init
it was easy to see that at91sam9x5_lowlevel_init.c was no
longer used.
Delete the file and the now unused CONFIG symbol and it uses

Subject: [PATCH 3/5] at91sam9263ek: move reset vector to board code
Create a new file at91sam926x_board_init.h which
is a copy of at91sam926x_lowlevel_init.c with a few minor
adjustments:
- We no longer call board code from this function
- The struct is renamed to avoid name clashes
- the function is rename to better match the prurpose
This file will be used in subsequent transformations
Otherwise just added the reset vector to the board code
and drop the now obsolete CONFIG selectst
