google/eve: Configure GPIOs for new board
A new board revision is making use of two previously unused GPIOs
to drive BOOT/RESET pins to an on-board MCU.
The reset pin is open drain so it is set as input by default, and
the boot pin is driven low by default.
Since these are UART0 pins they also need to be set up again after
executing FSP-S as it will change them back to native mode pins.
BUG=b:36025702
BRANCH=none
TEST=manual testing on reworked board, toggling GPIOs to put
the MCU into programming mode.
