soc/tegra: fuse: Correct straps' address for older Tegra124 device trees
[ Upstream commit 2d9ea1934f8ef0dfb862d103389562cc28b4fc03 ]
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register if machine uses an old outdated device tree.
