kbuild: Allow drivers to fit src/drivers/[X]/[Y]/ scheme

Reorder drivers to fit src/drivers/[X]/[Y]/ scheme to make
them pluggable.

Also, fix up the following driver subdirectories by switching
to the src/drivers/[X]/[Y]/ scheme as these are hard requirements
for the main change:

* drivers/intel
* drivers/pc80
* drivers/dec
