ota_from_target_files: Remove device dependent arguments

These device-specific arguments are defined at build time and are
necessary to generate the zip correctly. Don't use command line
arguments to specify them, but write all the needed information
in misc_info.txt when the target-files zip is generated.
ota_from_target_files will then read misc_info.txt and set
everything automatically.
