Bruce Richardson cf995efc53 drivers: clean up build lists 
Ensure all lists of drivers are standardized:
* one driver per line
* lists double-indented with spaces (as they are line continuations)
* elements in alphabetical order
* opening and closing list brackets "[" & "]" on own lines
* last element has trailing comma

Any code snippets in the list files is adjusted to single-indent using
whitespace to correspond to the new style also.

The lists of standard library dependencies per class, and other short
lists are not formatted one-per-line as these lists are not expected to
grow beyond 2 or 3 entries.
