mb/google/dedede/var/blipper: Update devicetree and gpio setting
To reduce power load, set unused GPIOs to NC and close
unused interface in devicetree. GPIOs and
interfaces are as below:
GPIO: GPP_C18/C19/D12/D14/D15/D19/D20/D21/E00/E02/H06/H07
Interface: I2C1/I2C3/I2C5
USB: port2_3/2_4/2_6
BUG=b:185044041
BRANCH=dedede
TEST=Built bios and test, it reduces power load without affecting
device function.
