ec: Re-configure GPIO02 to be INPUT | PULL_UP for power saving

GPIO02 (EC_HAVEN_RESET_ODL) is now configured to GPIO_ODR_HIGH,
designed for EC to reset H1. And it's no longer used with just
the HW path reserved (DNS R267 on schematic).
Tests showed that INPUT | PULL_UP has lower EC power consumption
so reconfiguring here.
