mb/google/brox: Disable Touchscreen for hardware board version 1
On board version 1 and later, touchscreen is not stuffed. Hence configure the relevant GPIOs as not connected, disable the concerned I2C bus in the devicetree as well as SoC chip config for board version 1. BUG=b:347333500 TEST=Build Brox BIOS image and boot to OS. Ensure that there are no peripherals detected in I2C 1 bus through i2cdetect tool. Ensure that no touchscreen devices are exported through ACPI SSDT table. Ensure that other I2C peripherals - eg. Trackpad and Ti50 are functional. Ensure that the device is able to suspend and resume for 25 cycles.
