Restructure the Tegra NVLINK IOCTL framework as follows:
    - Create an IOCTL struct for storing details about an IOCTL
    - Create an array of IOCTL structs and add entires for all existing
      IOCTLS
    - Simplifiy the ioctl() function so that it uses the IOCTL struct
      array to handle all IOCTLs

Cleanup IOCTL code as follows:
    - Add more error handling to the ioctl() function
    - Remove link ID and mask hardcoding in IOTCLs
    - Add "tegra" prefix to IOCTL enums which were missing this prefix
