For devices that have vidmem available, use the vidmem allocator in
gk20a_gmmu_alloc{,attr,_map,_map_attr}. For others, use sysmem.
Because all of the buffers haven't been tested to work in vidmem yet,
rename calls to gk20a_gmmu_alloc{,attr,_map,_map_attr} to have _sys at
the end to declare explicitly that vidmem is used. Enabling vidmem for
each now is a matter of removing "_sys" from the function call.

The cyclestats mode-e feature supported by userspace only
for t210 devices, so kernel should advertize it only for t210.
Also small check added to prevent BUG in dma-buf.c:826
if device has lack of memory.

There are two minor cleanups of cyclestats snapshots code implemented:
1. In case of unacceptably small buffer passed as a cyclestats snapshot
it causes a kernel panic during list element removal:
NvRmGpuTest_Channel_Cyclestats_Snapshot_Gen for 1 clients,
each has 4 KB mappings and 1 perfmons

2. Also fix with improved allocation of perfmon IDs implemented.

That is a kernel supporting code for cyclestats mode E.
Cyclestats mode E implemented following Windows-design in user-space
and required the following operations to be implemented:
- attach a client for shared hardware buffer of device
- detach client from shared hardware buffer
- flush means copy of available data from hardware buffer to private
client buffers according to perfmon IDs assigned for clients
- perfmon IDs management for user-space clients
- a NVGPU_GPU_FLAGS_SUPPORT_CYCLE_STATS_SNAPSHOT capability added
