msm: kgsl: add userspace memory alloc and free tracepoints
Add events for tracking memory operations by userspace
clients: kgsl_mem_alloc, kgsl_mem_map, kgsl_mem_free,
kgsl_mem_timestamp_queue (adding an entry to the free
on timestamp list) and kgsl_mem_timestamp_free (when
the memory is actually freed).
