mb/google/octopus: Configure EC_IN_RW correctly

This change fixes the following issues with EC_IN_RW signal:
1. EC_IN_RW is an input signal to the SoC. Configure it accordingly in
GPIO table for baseboard and bip.
2. GPIO_EC_IN_RW is passed in coreboot tables so that payload can
re-sample the GPIO at runtime.

BUG=b:110084012
TEST=Verified that EC_IN_RW signal is read correctly in depthcharge.
