whitespace and indentation fixes

Replace tabstops, correct indentation according to Lattice's coding style. This huge patch makes it harder to backport upstream fixes, but there was already a patch which replaced almost every line in the source code. So it was already hard :) Signed-off-by: Michael Walle <michael@walle.cc>
