gpu: nvgpu: add syncpoint read map

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.
