gpu: nvgpu: remove use of multichar constants

Browse Source 
In gk20a.h, we use these multichar constants
'DONE', '0R32', '0W32'

But these constants fail compilation on some cross-os compilers
Hence remove them by creating a specific MULTICHAR_TAG()

All the User space components also form these constants in similar
fashion
