Revert "wifi: iwlwifi: make no_160 more generic"

This reverts commit 75a3313f.

The indication of the BW limitation in the sub-device ID is not applicable
for Killer devices. For those devices, bw_limit will hold a random value,
so a matching dev_info might not be found, which leads to a probe
failure.
Until it is properly fixed, revert this.
