The option CONFIG_TEGRA_FUSE_UPSTREAM is not needed any longer because
we always want to enable this for Linux v5.15. Therefore, remove this
option completely.
The function tegra_fuse_control_read() is not used anywhere and so we
can also remove this too.

The fuse function tegra_get_sku_id() does not exist in upstream and so
when building downstream drivers against an upstream kernel, the build
fails. The tegra_get_sku_id() calls the function tegra_fuse_readl()
which is supported in upstream and exported so can be used by external
kernel modules. The implementation of the tegra_get_sku_id() has been
moved to the header file 'fuse-helpers.h' that can be used by drivers
and allow drivers to be built as external modules. Therefore, migrate
drivers to use this implementation so we can move the implementation
from the downstream kernel.

When building the CVNAS driver as an external module against upstream
Linux kernels, there are some downstream fuse APIs that are not found.
To fix building CVNAS for upstream kernels ...
1. Use the device-tree machine compatibility string instead of the
downstream fuse function tegra_get_chip_id().
2. For the functions tegra_platform_is_silicon() and
tegra_platform_is_sim() add implementations in a fuse-helper.h
that always assume that platform is silicon and not a simulator.
Note this assumption is only applied to upstream kernels and
downstream kernel still use the downstream implementation. Long
term we need to revisit this.
3. Copy the downstream implementation for function tegra_get_sku_id()
to the fuse-helper.h so that this is available for upstream kernels.
The functions implemented in fuse-helper.h are only used if the compiler
flag CONFIG_TEGRA_FUSE_UPSTREAM is defined.
