We will now dump MAC, APU, CIU, ICU firmware memory segments also
for PCIe interface. Following is the updated userspace script which
reads firmware dump information.

    mwifiex_pcie_fw_dump.sh: #!/bin/bash
    ethtool --set-dump mlan0 0
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/ITCM.log

    ethtool --set-dump mlan0 1
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/DTCM.log

    ethtool --set-dump mlan0 2
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/SQRAM.log

    ethtool --set-dump mlan0 3
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/IRAM.log

    ethtool --set-dump mlan0 4
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/APU.log

    ethtool --set-dump mlan0 5
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/CIU.log

    ethtool --set-dump mlan0 6
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/ICU.log

    ethtool --set-dump mlan0 7
    ethtool --get-dump mlan0
    ethtool --get-dump mlan0 data /tmp/MAC.log
