For sync-point read map:
1. Added nvgpu_mem memory allocator in gk20a struct and
allocated memory for this in gk20a_finalize_poweron()
and freed this memory in gk20a_remove().
2. Added "u64 syncpt_ro_map_gpu_va" in vm_gk20a struct
for read map in vm.
Added nvgpu_quiesce() in nvgpu_remove() before freeing
syncpoint read map to ensure that nvgpu is idle.
