gpu: nvgpu: use nvgpu specific nvhost APIs

Remove use of linux specifix header files
<linux/nvhost.h> and <linux/nvhost_t194.h>
and use nvgpu specific header file
<nvgpu/nvhost_t19x.h> instead
This is needed to remove all Linux dependencies
from nvgpu driver

Replace all nvhost_*() calls by
nvgpu_nvhost_*() calls from new nvgpu library
