gpu: nvgpu: use nvgpu specific nvhost APIs

Remove use of linux specifix header files
<linux/nvhost.h> and <linux/nvhost_ioctl.h>
and use nvgpu specific header file <nvgpu/nvhost.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

Remove platform device pointer host1x_dev
from struct gk20a and add struct
nvgpu_nvhost_dev instead
