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.
