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.

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.

The arbiter is charged with selecting the proper
frequencies when multiple applications submit
simultaneously clock change requests
On the current implementation, the arbiter guarantees
that the selected frequency will be always higher
or equal to the request, as long as the request is
in range.
The current code is not yet realtime friendly, as
requests are not pre-allocated.
Summary of changes:
(1) pstate/vf switch no longer selects boot frequency
(2) changed mclk code change to accept input freq
(3) added arbiter
(4) now a single session can submit concurrent requests
the last request is the one that applies for that
session
(5) modified locking mechanism to reduce lock contention
(6) Added callback to notify the arbiter that the VF
table has changed and is no longer valid (PMU/Thermals
must call this when VF table is invalid)
(7) changed internal API to work with MHz
(8) added debugfs for stats

Fix small problems related to signed versus unsigned comparisons
throughout the driver. Bump up the warning level to prevent
such problems from occuring in future.

- Read voltage tables from VBIOS & construct
then send to PMU.
- compare & set voltage based on
mclk/gpc2clk clk, take higher voltage
between two & set.
