google/reef: ACPI: Move touchpad to SSDT and remove TPM
Instantiate the touchpad using the drivers/i2c/generic device driver
to generate the ACPI object in the SSDT.
There is not currently a separate wake pin for this device, this will
be added in EVT hardware.
This was tested on the reef board by ensuring that the touchpad device
continues to work in the OS.
Also remove the LPC TPM from the DSDT as it is not present.
