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.
