Dear Maintainer,

While working on the “reproducible builds” effort [1], we have noticed
that fpga-icestorm-chipdb could not be built reproducibly: the order of
".pins" sections in chipdb-1k.txt and chipdb-8k.txt is random [2].

The attached patch ensures a stable section order in those two files.
I believe with this patch, fpga-icestorm will be fully reproducible.

Best,

Daniel
