video: tegra: Migrate to fuse helpers

Browse Source 
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.
