This patch includes a number of small changes for integrating the
AT91SAM9261 and AT91SAM0260 support.
* Can only select support for one AT91 processor at a time.
* Remove most of the remaining static memory mapping for the
AT91RM9200.
* Reserve 1Mb of memory below the IO for mapping the internal SRAM
and any custom board-specific devices (ie, FPGA).
* The SAM9260 has more serial ports, so increase the maximum to 7.
* Define the standard chipselect addresses, and define other
addresses relative to those.
* CLOCK_TICK_RATE is different on the SAM926x's.
