Dont perform reset at the end of thor download
if configured to do reset off.
Reset may not be required in all cases and hence
provided an option to do so.

Hi,

You fail to explain in which cases this option is needed.
You also fail to document this option in README file.

Please fix.

Best regards,

The case here would be to download the images just to DDR instead of to any flash device.

Just ignore it. I will update the commit message and will resend this
patch as v2 but I will wait if someone else has any objection with it.
