rGac8d9f5c8968: stand: Introduce devparse to parse device / path strings
rG781ca0afcd6c: stand: Introduce devparse to parse device / path strings
Summary

devparse is now the preferred interface to use to parse device
strings or device:/path strings. It parses the passed in string,
mallocs the device's particular devdesc string and returns the
'remainder' of the device:/path for further processing.
