Subject: soc/tegra: fuse: Warn if straps are not ready
Git-commit: c71f213fa5afae40cc7e5365585f5cdc51b135df
Patch-mainline: v5.6-rc1
References: jsc#SLE-15847
Now both Chip ID and HW straps are becoming available at the same time,
thus we could simply check the availability of the ID in order to check
the availability of the straps. We couldn't check straps for 0x0 because
it could be a correct value.
This change didn't uncover any problems, but anyways it is nicer to have
straps verified for consistency with the Chip ID verification.
