Reorganize the HW headers of gk20a. The headers are moved to a new directory: include/nvgpu/hw/gk20a And from the code are included like so: #include <nvgpu/hw/gk20a/hw_pwr_gk20a.h> This is the first step in reorganizing all of the HW headers for gm20b, gm206, etc. This is part of a larger effort to re-structure and make the driver more readable and scalable.
