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.
