Add Netgear WNCE2001 (OF version)

Add Netgear WNCE2001.

This is a small RT3052 device with 4MB spi flash and 32MB ram.
2 built-in antennas, 1x fastE, no USB, reset & wps switch.
On my model the AP/RT switch is unpopulated, but I verified the gpio
mapping for it.
The stock firmware is running an unprotected tftpd which allows you
to read any file from the filesystem.
Serial port is present on testpads (See image on the wiki page).
There are more testpads below the shield near the SoC, which
may have JTAG.

Slight annoyance: The bootloader is checksumming kernel&rootfs, but
can be tricked by zeroing checksum and length fields in the checksum
partition, see
target/linux/ramips/base-files/lib/preinit/04_disable_wnce2001_flash_checksumming

The manufacturer image is very similar to the DAP one, so I slightly
modified mkdapimg to support generating it.

The resulting
openwrt-ramips-rt305x-wnce2001-squashfs-factory-(worldwide|northamerica).bin
can be used to flash from stock to OpenWRT using the stock firmware
upgrade function, without using the serial port.
