Add (basic) support for W83977EF Super-IO chip. This is based on w83977tf code and on earlier support for this chip in superiotool.
Signed-off-by: Andriy Gapon avg@icyb.net.ua
--- This was done by copy'n'paste of w83977tf, substitution of w83977tf with w83977ef, and then some chip-specific changes in the list of logical devices in w83977tf.h and their resources in superio.c:pnp_dev_info.
The code was not tested yet on real hardware (and there is no mobo in the src to use it yet), but I believe that it should work - based on triviality of the changes and hardware specs.
As my changes were fairly minimal I left all copyrights as they were in w83977tf code.

As trivial change as it was I still managed to make a couple of mistakes (not all files renamed, one old resource line not removed). Now this is compile tested with slightly modified msi/ms6147.
