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.
