gpu: nvgpu: split nvhost dependency on plat interface

Add CONFIG_TEGRA_GK20A_NVHOST and remove the TEGRA_GRHOST ||
TEGRA_HOST1X dependency in CONFIG_TEGRA_GK20A to allow using the iGPU
without the nvhost driver. Use the new config to guard syncpt-related
code.

Also make TEGRA_ACR depend on GK20A too so that it aligns properly under
gk20a in menuconfig.
