Speedup sis-updater by adding parameter to assume a single device

The touch is not responsive until sis-updater has completed, so
it is important to keept the runtime as low as possible when
no upgrade is needed. This cuts about 2 seconds of runtime.

BUG=b:65213465
TEST=Tested --recovery manually and no-upgrade using udev on CFM
