Stanley Wu has uploaded this change for review.
mb/google/volteer: Update I2C5 bus freq and trackpad gpio settings.
Update lindar gpio settings for Synaptics trackpad no function issue.
Update I2C5 bus freq to 400kHz.
BUG=b:160013582
TEST=emerge-volteer coreboot and check system dmesg and evtest can get
device. Verify trackpad function workable.
