gpu: nvgpu: array of pointers to runlists

Browse Source 
Currently a fifo_runlist_info_gk20a structure is allocated and
initialized for each possible runlist. But only a few runlists
are actually used.

Use an array of pointers to runlists in fifo_gk20a. The array
keeps existing indexing by runlist_id. In this patch a context
is still allocated for each possible runlist, but follow up
patch will allow to skip context allocation for inactive
runlists.
