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)
