mb/google/hatch: 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(). Additionally, this change moves mainboard_ec_init() to mainboard dev->init(). TEST=Verified that GPIOs are configured properly and hatch boots to OS.
