i2c: add support for timeout configuration at runtime
When the EC sends longer commands to the PD chip (such as flash
erase/write over the passthru from AP), allow it to take a second
instead of the default 100ms timeout.
BUG=chrome-os-partner:30935
BRANCH=none
TEST=samus boots
battery command works from EC console
ectool passthru of flash erase to PD works (requires hacked ectool)
