Alex Waterman 78ad8a23ea gpu: nvgpu: Move gp106 HW headers
Move the gp106 HW headers to a new directory specially for them:

  include/nvgpu/hw/gp106

And change the code to include like so:

  #include <nvgpu/hw/gp106/hw_fb_gp106.h>

This is part of the process to restructure the nvgpu driver.

Bug 1799159
