1) Update header path of gk20a.h files present in os/
to <nvgpu/gk20a.h>
2) os_fence_android_sema.c indirectly was dependent on gk20a.h via
semaphore.h. So, added #include <nvgpu/gk20a.h> in
os_fence_android_sema.c and replaced the header with forward
declaration of struct gk20a in semaphore.h

This flag - has_physical_mode - doesn't seem to do much other than
force the PTE/PDE and inst block addresses to be physical instead
of potentially IOMMUed.
There is a reason to do this on volta (nvlink not being IOMMU'able
being the primary reason) but this flag is too general it seems.
The flag was being enabled on all native platforms. The problem is
that some page tables (the maxwell small page directories) could
be larger than 4KB which meant that the allocation used for them
could be potentially discontiguous. Discontiguous page directories
obviously is incorrect.
This patch deletes the has_physical_mode flag and instead replaces
the places where it's checked with a check for nvlink being
enabled. Since we _do_ want to program phyiscal PDEs and PTEs for
NVLINK devices (regardless of IOMMU status they always access
memory by physical address) we need a check for NVLINK state.

During driver remove, if nvlink is set up, gracefully
shut it down so that it can be enumerated again.

- create common file common/ecc.c which include common functions for add
ecc counters and remove counters.
- common code will create a list of all counter which make it easier to
iterate all counters.
- Add chip specific file for adding ecc counters.
- add linux specific file os/linux/ecc_sysfs.c to export counters to
sysfs.
- remove obsolete code
- MISRA violation for using snprintf is not solved, tracking with

Runtime PM is enabled only for iGPU and not for dGPU. For dGPU,
the .probe() of driver pm_runtime_disable()s, if rail-gating is
not enabled. With nvgpu kernel module load/unload, .probe() is
called multiple times for same struct device *. This results
in an overflow of disable_depth (3 bit refcount) and enables
runtime PM on 8th iteration and calls RTPM routines even if it's
disabled.
To effectively manage pm_runtime_disable(), move it from common
nvgpu_remove() to iGPU/dGPU specific routines.
Also, add restore pm_runtime state of device on driver .remove().

While removing nvgpu driver, devm mapped reg mappings
are released on driver_unregister. For iGPU, these
regs are explicitly unmapped with iounmap(). This
results in "Trying to vfree() nonexistent vm area"
warnings on driver removal.
Address this by using devm* variants to map all IO regions
of both iGPU and dGPU and let the driver unregister
release these mappings.
Also, lock out GPU regs in driver removal path.

Move all Linux source code files to drivers/gpu/nvgpu/os/linux from
drivers/gpu/nvgpu/common/linux. This changes the meaning of common
