eve: PROCHOT behavior fixes
1) Don't assert prochot by default, this signal has an inverter
and driving it high is asserting prochot until it gets deasserted
during S3->S0 transition.
2) Clear PMIC power source interrupts in pmic_init in case they
were inadvertently set by misbehaving PMIC. The BATTSHORT event
that matters for PROCHOT assertion is masked so it should never
be set anyway, but I found a system where it was set. This register
does not seem to get cleared by an LDO reset so PROCHOT was stuck on
until battery cutoff.
