soc/tegra: fuse: Correct straps' address for older Tegra124 device trees
Trying to read out Chip ID before APBMISC registers are mapped won't succeed, in a result Tegra124 gets a wrong address for the HW straps register if machine uses an old outdated device tree. Fixes: 297c4f3dcbff ("soc/tegra: fuse: Restrict legacy code to 32-bit ARM") Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
