gpu: nvgpu: allocate secure buffer in probe
Allocate dummy secure buffer of size PAGE_SIZE during gk20a_probe().
This will also help to initiate first secure memory (VPR)
resize call while GPU is rail gated and in reset.
This dummy buffer is released after we allocate some more
secure memory buffers in alloc_global_ctx_buffers()
