4b889fb8b0 gpu: nvgpu: use devm variants to ioremap 
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.

f403800dce gpu: nvgpu: move can_railgate to enabled.h 
The g->can_railgate flag is a global constant-ish property like the rest
of the flags behind nvgpu_is_enabled() API, so move it there.

2a2c16af5f gpu: nvgpu: Move Linux files away from common 
Move all Linux source code files to drivers/gpu/nvgpu/os/linux from
drivers/gpu/nvgpu/common/linux. This changes the meaning of common
to be OS independent.
