lantiq: add Falcon support
This adds support for the Intel Falcon SoC for GPON. Support for the Falcon SoC was removed in commit c8218363951 svn rev: 40392 from OpenWrt, this commit adds it again. This patch adds a new subtarget for the Falcon SoC, but it still misses all the drivers needed to control the GPON part. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
