Log: OLPC ARM: convert s3-selftest to use sus power measurement
ec-sus-pwr reads a power measurement from the EC that only happens after the EC senses the SoC is in suspend. This reading gives much more consistent results as long as the SoC is suspended for long enough for the EC to update. (1s or more)
