meta-yocto-bsp: oeqa/controllers: add EdgeRouterTarget

Based on BeagleBoneTarget, this provides support for deploying images
and running tests on an EdgeRouter Lite (edgerouter). The device must
be set up to boot into the master image already - see the instructions
in the file.

Implements [YOCTO #6253].

+# This module adds support to testimage.bbclass to deploy images and run
+# tests on a Ubiquiti Networks EdgeRouter Lite. The device must be set up
+# to boot into the master image already - the easiest way to do that is as
+# follows:
+#
+# 1. Take out the internal USB drive and plug it into your PC
+# 2. Repartition the USB drive so that you have three partitions in this
+#    order:
+#      1: vfat, labelled "boot" (it will need to be formatted with mkfs.vfat
+#         for this to be possible, since FAT partitions formatted under
+#         DOS/Windows will only support uppercase labels)
+#      2: ext3 (for master image) labelled "testmaster"
+#      3: ext3 (for image under test) labelled "testrootfs"
+# 3. Copy the kernel to be used by the master image to the FAT partition
+#    (it should be named "vmlinux.64" with the factory u-boot configuration)
+# 4. Install the master image onto the "testmaster" ext3 partition. If
+#    you do this by just extracting the contents of an image onto the
+#    partition, you will also likely need to create the master image marker
+#    file /etc/masterimage within this partition so that we can tell when
+#    we're booted into it that it is the master image.
+# 5. Put the USB drive back into the device, and ensure the console port
+#    and first ethernet port are connected before powering on
+#
+# TEST_SERIALCONTROL_CMD will need to be set in local.conf so that we can
+# interact with u-boot over the serial console port.
