ar71xx: drop target

This target has been mostly replaced by ath79 and won't be included
in the upcoming release anymore. Finally put it to rest.

This also removes all references in packages, tools, etc. as well as
the uboot-ar71xx and vsc73x5-ucode packages.

-Subject: [PATCH] Reproducible U-Boot build support, using SOURCE_DATE_EPOCH
-
-In order to achieve reproducible builds in U-Boot, timestamps that are defined
-at build-time have to be somewhat eliminated. The SOURCE_DATE_EPOCH environment
-variable allows setting a fixed value for those timestamps.
-
-Simply by setting SOURCE_DATE_EPOCH to a fixed value, a number of targets can be
-built reproducibly. This is the case for e.g. sunxi devices.
-
-However, some other devices might need some more tweaks, especially regarding
-the image generation tools.

-+Reproducible builds
-+-------------------
-+
-+In order to achieve reproducible builds, timestamps used in the U-Boot build
-+process have to be set to a fixed value.
-+
-+This is done using the SOURCE_DATE_EPOCH environment variable.
-+SOURCE_DATE_EPOCH is to be set on the build host's shell, not as a configuration
-+option for U-Boot or an environment variable in U-Boot.
-+
-+SOURCE_DATE_EPOCH should be set to a number of seconds since the epoch, in UTC.
