Remove static dev node meta data from struct nvgpu_os_linux and replace it by a dynamic list. Struct nvgpu_os_linux will only keep track of list head and number of entries. Add new structure nvgpu_cdev to store meta data of each dev node and create/setup it dynamically in gk20a_user_init(). Once done, add the new node under list head maintained in nvgpu_os_linux. Add a static list dev_node_list[] that contains list of dev node names and file operations. This static list is used to create nvgpu_cdev data structures and to register new device nodes. Update all dev node open file operations (e.g. gk20a_as_dev_open()) to extract struct gk20a pointer from device pointer of dev node. gk20a device is the parent of dev node device.
