reg_script: add reg_script_run_on_dev()

The reg_script library has proven to be useful. It's
also shown that many scripts operate on devices. However,
certain code paths run the same script on multiple,
but different, devices. In order to make that easier
introduce reg_script_run_on_dev() which takes a device
as a parameter. That way, chained reg_scripts are not
scrictly needed to run the same script on multiple devices.

BUG=None
BRANCH=None
TEST=Built.
