Add glue/support for the SAM9XE512-based Ethernut 5 boards. Currently,

all integrated and on-board peripherals except the DataFlash (at91_spi(4)
and at45d(4) still need to be unb0rken) and NAND Flash (missing NAND
framework) are working.
AFAICT, this makes FreeBSD the first operating system besides Nut/OS
supporting Ethernut 5 out of tree.
