As we aren't quite able to convert some platforms with a very small size
limit in SPL yet, we need to revert this for now.
This reverts commit 7b0947787358c6b277431d6b76ce043d8bec641d.

move CONFIG_SYS_SPI_WRITE_TOUT into drivers/spi/atmel_spi.h
and define a default value. Delete this define in the board
config files, where it is possible (all boards use currently
the same value).

This adds a driver for the SPI controller found on most AT91 and AVR32
chips, implementing the new SPI API.
Changed in v4:
- Update to new API
- Handle zero-length transfers appropriately. The user may send a
zero-length SPI transfer with SPI_XFER_END set in order to
deactivate the chip select after a series of transfers with chip
select active. This is useful e.g. when polling the status
register of DataFlash.
