avr32: Add support for ATSTK1006

Browse Source 
The ATSTK1006 is basically an upgraded version of ATSTK1002 with
128 MiB SDRAM and 256 MiB NAND flash on board.

Otherwise, the board is very similar to the ATSTK1002, so it uses the
same board support file.

/*
* The ATSTK1006 daughterboard is very similar to the ATSTK1002. Both
* have the AT32AP7000 chip on board; the difference is that the
* STK1006 has 128 MB SDRAM (the STK1002 uses the 8 MB SDRAM chip on
* the STK1000 motherboard) and 256 MB NAND flash (the STK1002 has
* none.)
*
* The RAM difference is handled by the boot loader, so the only
* difference we end up handling here is the NAND flash.
