aleksander/qmi-firmware-update v2: dms-list-stored-images on MC7430

[Christophe Ronco]

On my side, I put firmware 2.14, 2.20 and 2.23 on my MC7430:

First, I don't have to reboot my board after a dms-select-stored-image, 
I just have to be patient. After reset modem devices disappear, one 
minute later they reappear, next command ends with timeout and then 
modem is back alive.
I was power cycling my modem or my board but that was just because I am 
not patient enough.

I tried to select the three stored images one after the other. Here are 
my results:

So for 2.20 and 2.23, index_of_running_image seems to be image storage 
index and for 2.14, index_of_running_image seems to be imageindex in list.

I don't understand the logic behind that.
