gpu: nvgpu: create symbolic link for gpu device under /sys/devices/

Browse Source 
In linux kernel v4.14 and below gpu sysfs node is created under
/sys/devices. In linux kernel v5.x it is created under
/sys/devices/platform.

Create symbolic link for the gpu device ("17000000.gv11b") under
/sys/devices/ as various tests and scripts expect it to be there.
