Alex Waterman 6dd57c29b0 gpu: nvgpu: Move gm206 HW headers
Move the gm206 HW headers to a new directory specially for them:

  include/nvgpu/hw/gm206

And change the code to include like so:

  #include <nvgpu/hw/gm206/hw_fb_gm206.h>

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

Bug 1799159
