iwlwifi: mvm: add iccm data to 8000 b-step data dump
In 8000 HW family B-step only, the ICCM is separate from the SRAM. This adds the ICCM to the dump data collected for FW debug. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Reviewed-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
