mwifiex: add more dump information for PCIe interface

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
