Nami: Delay and repeat gas gauge detection
Currently, battery gas gauges are detected only once at HOOK_INIT. This
is too early when a battery wakes up from cutoff.
This patch makes EC detect gas gauges when needed. On Nami this is
when the power button task checks power readiness. The power button
task then repeatedly performs this check until a gauge wakes up.

1. Write protect EC SPI flash
2. Unplug AC charger
