drivers: serial: jsm: Enable support for Digi Classic adapters

소스 검색 
This commit enables support for the Digi Classic adapters line in the
jsm driver. This means changes in:
	- device probing code
	- device cleanup code
	- driver description (Kconfig)

The init/cleanup code is based on the staging/dgnc driver.
