9dd2a8fc73 gpu: nvgpu: Get GA10B EMC floorsweeping status 
The memory bandwidth reported by the nvgpu driver is a resultant of FBP and EMC floorsweeping status. The FBP floorsweep status was already getting reported in the GPU characterstics so the status of EMC was fetched and reported in this change.

ad85b60bb0 gpu: nvgpu: use nvmem API to read fuses 
Replace the usage of tegra_fuse_readl with nvmem_cell_read_u32 for the
below fuse registers added as nvmem cells on v5.10+ kernels.

Older nvidia kernels do not have these tegra nvmem cell support.

b117f40f6c gpu: nvgpu: separate tegra fuse read from under CONFIG_NVGPU_TEGRA_FUSE 
tegra_fuse_readl is supported in upstream. Separate out the functions
using this API from the config CONFIG_NVGPU_TEGRA_FUSE.

Following four fuses are defined in downstream kernel repositories in
tegra fuse header. It can be incorporated in upstream if nvgpu starts
reading those fuses using nvmem APIs. Hence define those fuse offsets
in nvgpu itself for now.
