asix-sigma: Suspend support for trailing DRAM lines

asix-sigma: Suspend support for trailing DRAM lines

The support for trailing DRAM lines was broken. This patch starts
rework of support for this, but in order to do that, we need to
rework decode_chunk_ts() a little first.

This patch adjusts the decode_chunk_ts() a little to receive the
total amount of events in DRAM line instead of some nonsense value.
This patch temporarily removes the support for the trailing DRAM
lines until the decode_chunk_ts() is fixed to cope with this, so
yes, this patch introduces breakage!
