mb/google/{drallion,sarien}: Configure GPIOs in mainboard chip->init()

mainboard_silicon_init_params() is supposed to be used for only
overriding any FSP params as per mainboard configuration. GPIOs should
be configured by mainboard as part of its chip init(). This ensures
proper ordering w.r.t. any common operations that the SoC code might
want to perform e.g. snapshot ITSS polarities.

This change moves the configuration of GPIOs from
mainboard_silicon_init_params() to mainboard chip->init().
