This reverts commit 335bc46d

.

The revert of the acpuclock table to lower voltages did indeed
improve stability, but was not the underlying root cause of the
reported failures.

It turns out that a hardware bug prevented the PMIC regulator
MODE_CTL register from being reset in WARM_RESET. Consequently,
we often left the regulator running in PFM mode. This is bad,
since our software assumes the default value is PWM. Thus we
would often end up bringing up cores at higher current
requests than that tolerated in PFM mode, and crash the system.
