mvebu: 5.10 fix DVFS caused random boot crashes

5.10.37 and 5.4.119 introduced a lot of DVFS changes for Armada 37xx from 5.13 kernel.

Unfortunately commit:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/drivers/cpufreq/armada-37xx-cpufreq.c?h=v5.10.37&id=a13b110e7c9e0dc2edcc7a19d4255fc88abd83cc

This patch actually corrects the things so that 1 or 1.2GHz models would actually get scaled to their native frequency.

However, due to a AVS setting voltages too low this will cause random crashes on 1.2GHz models.

So, until a new safe for everybody voltage is agreed on
lets revert the patch.

Fixes: d337731 ("kernel: bump 5.10 to 5.10.37")
