gpu: nvgpu: add APIs to export fuse offsets

Add below new APIs in common/linux/fuse.c and export them from
include/nvgpu/fuse.h to read/write specific tegra fuse offsets

void nvgpu_tegra_fuse_write_bypass(u32 val);
void nvgpu_tegra_fuse_write_access_sw(u32 val);
void nvgpu_tegra_fuse_write_opt_gpu_tpc0_disable(u32 val);
void nvgpu_tegra_fuse_write_opt_gpu_tpc1_disable(u32 val);
int nvgpu_tegra_fuse_read_gcplex_config_fuse(u32 *val);
int nvgpu_tegra_fuse_read_reserved_calib(u32 *val);

These APIs are needed to remove nvgpu's direct
dependency on platform specific <soc/tegra/fuse.h> header

Remove below generic APIs since they are no longer needed :
nvgpu_tegra_fuse_read()
nvgpu_tegra_fuse_write()
