ramips: add support for Airlink101 AR670W

This is a RT2880-based board, 32MB RAM, 4MB flash. The bootloader
is a hacked u-Boot that reads an LZMA image directly, so we skip
generating the uImage header and enable the lzma mtdsplit parser.

Add more license tags with SPDX identifiers

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.

I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.

However, I can not garantee that I always picked the correct information
and/or did not miss license information.
