Instead of using the old-style base + offset accessors, use the new at91 C struct accessors.

The removal of #ifdef CONFIG_AT91_LEGACY allows to keep the definition of register values, needed to program the SPI.

Since all users of at91_spi have been converted to C struct accessors, the register offsets definitions are no longer needed.

We take this opportunity to do a little bit of reformatting for the register bits definitions.

The Calao USB A9263 board is a board manufactured and sold by Calao Systems http://www.calao-systems.com. Its components are very similar to the AT91SAM9263EK board, so its configuration is based on the configuration of this board. There are however some differences: different clocks, no LCD, etc.
