arm: Remove ethernut5 board

As per the maintainers at egnite GmbH, they are no longer interested in
supporting this board. Go and remove the platform here. Furthermore,
this is the only AT91SAM9XE platform in-tree so remove supporting code
for that as well.

- * Ethernut 5 general board support
- *
- * Ethernut is an open source hardware and software project for
- * embedded Ethernet devices. Hardware layouts and CAD files are
- * freely available under BSD-like license.
- *
- * Ethernut 5 is the first member of the Ethernut board family
- * with U-Boot and Linux support. This implementation is based
- * on the original work done by Ole Reinhardt, but heavily modified
- * to support additional features and the latest board revision 5.0F.
- *
- * Main board components are by default:
- *
- * Atmel AT91SAM9XE512 CPU with 512 kBytes NOR Flash
- * 2 x 64 MBytes Micron MT48LC32M16A2P SDRAM
- * 512 MBytes Micron MT29F4G08ABADA NAND Flash
- * 4 MBytes Atmel AT45DB321D DataFlash
- * SMSC LAN8710 Ethernet PHY
- * Atmel ATmega168 MCU used for power management
- * Linear Technology LTC4411 PoE controller
- *
- * U-Boot relevant board interfaces are:
- *
- * 100 Mbit Ethernet with IEEE 802.3af PoE
- * RS-232 serial port
- * USB host and device
- * MMC/SD-Card slot
- * Expansion port with I2C, SPI and more...
- *
- * Typically the U-Boot image is loaded from serial DataFlash into
- * SDRAM by the samboot boot loader, which is located in internal
- * NOR Flash and provides all essential initializations like CPU
- * and peripheral clocks and, of course, the SDRAM configuration.
- *
- * For testing purposes it is also possibly to directly transfer
- * the image into SDRAM via JTAG. A tested configuration exists
- * for the Turtelizer 2 hardware dongle and the OpenOCD software.
- * In this case the latter will do the basic hardware configuration
- * via its reset-init script.
- *
- * For additional information visit the project home page at
- * http://www.ethernut.de/

- * Ethernut 5 power management support
- *
- * This board may be supplied via USB, IEEE 802.3af PoE or an

- *
- * Two distinct registers are provided by the PMC for enabling
- * and disabling specific features. This avoids the often seen
- * read-modify-write cycle or shadow register requirement.
- * Additional registers are available to query the board

- * the green user LED that is integrated in the reset switch.
- *
- * Note, that the AVR firmware of the PMC is released under BSDL.
