[U-Boot] Support for Calao USB A9263 board based on AT91SAM9263 CPU

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.

This new version includes the following changes :
* Copyright header on config.mk, by suggestion of Peter Tyser
* Updated copyright informations in all new files
* Use get_ram_size(), as suggested by Wolfgang Denk
* Do some cleanup of useless comments, re-indent definitions to avoid
long lines, etc.
* Add entry to MAINTAINERS
I'm still including the definition of ROUND() in the board
configuration file, since Wolfgang's patch has yet been merged to the
Git tree (and I don't think sending a patch that doesn't compile
against the current Git tree is useful).
