Move source files to driver/ and power/ subdirs

The common/ subdir was getting cluttered.  Move drivers for external
components to a new driver/ tree, and move what used to be called
chipset_*.c to a new power/ directory.

This does not move/rename header files or CONFIG options.  That will
be done in subsequent steps, since moving and modifying .c files in
the same CL is harder to review.
