Randall Spangler	a528f89291	Use mutex for EC->PD host commands ... Host commands can be generated by either the PDCMD task (in response to PD interrupts), or the HOSTCMD task (in response to passthru requests). Use a mutex to serialize access to the EC->PD interface.

Randall Spangler	4692a1387a	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.
