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.
