Anup Mahindre 75ff0feeff gpu: nvgpu: Add characterstics field to expose max ctxsw ring buffer size ...

NVGPU_CTXSW_IOCTL_RING_SETUP can be used to setup a custom ring buffer
and it accepts size via arguments. nvgpu driver will return an error
if size requested is greater than 128 * 4096 but this value is hardcoded
and not exposed anywhere.
Add characteristics field in nvgpu.h to expose this size so that corresponding
nvrm_gpu API can use it.
