mb/google/volteer: Update I2C5 bus freq and devicetree.
Update lindar gpio settings for Synaptics trackpad no function issue.
Update I2C5 bus freq to 400kHz.
Improve Goodix Touchscreen power on sequence.
BUG=b:160013582
BRANCH=firmware-volteer-13521.B
TEST=emerge-volteer coreboot and check system dmesg and evtest can get
device. Verify trackpad function workable.
