mb/google/octopus: Enable pull on ESPI_IO1 line

This change configures a weak internal pull-up on ESPI_IO1 line for
octopus baseboard and variant bip. ESPI_IO1 is used as ALERT# line and
is expected to be open-drain. However, there is no external pull on
this line and so an internal pull-up is required to ensure proper eSPI
communication.

BUG=b:78497502
TEST=Verified that there is no eSPI communication failure between AP
and EC during boot-up and on suspend/resume.
