Device megapatch 1/6:

Free approx 86 major numbers with a mostly automatically generated patch.

A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.

Minor changes:
[1] Support the Sony VAIO Jogdial in moused(8).
[2] Modify spic(4) to support additional Sony VAIO models.

Add the spic driver, which is a simple first attempt at providing access
to the jog dial device.
