tegra-nvlink-uapi.h is used by nvrm_gpu, and is causing some MISRA
violations.
A number of MISRA C++ 2008 rules require U suffix for unsigned
numbers.
2-13-3 A "U" suffix shall be applied to all octal or hexadecimal
integer literals of unsigned type.
5-0-4 An implicit integral conversion shall not change the signedness
of the underlying type.
5-0-21 Bitwise operators shall only be applied to operands of unsigned
underlying type.

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

Below updates are made to tegra nvlink ioctl header file:
* tegra-nvlink-mods.h file is moved to include/uapi/linux/
* Rename tegra-nvlink-mods.h file to tegra-nvlink-uapi.h
* Use specific macros like _IOR/_IOW for read-only/write-only IOCTLs.
* Every name in header file should have a "tegra_" prefix to avoid name
clashes with RM enums/structs/ioctl names.
