cpufreq: ti-cpufreq: Use socinfo to get revision in AM62 family
In the AM62x, AM62Ax, and AM62Px devices, we already have the revision
info within the k3-socinfo driver. Hence, re-use this information from
there instead of re using the offset for 2 drivers trying to get the
same information ie. revision.
