google/rambi: Fix IASL warnings _CRS must return a value
The Touchpad and Touchscreen _CRS methods do not return an interrupt
value if the I2c busses that the devices are on are not in PCI mode.
Previously they didn't return any value if they weren't in PCI mode.
This patch has them return an empty resource template.
Fixes these warnings:
dsdt.aml 2813: Method (_CRS)
Warning 3115 - ^ Not all control paths return a value (_CRS)
dsdt.aml 2813: Method (_CRS)
Warning 3107 - ^ Reserved method must return a value
(Buffer required for _CRS)
dsdt.aml 2832: Method (_CRS)
Warning 3115 - ^ Not all control paths return a value (_CRS)
dsdt.aml 2832: Method (_CRS)
Warning 3107 - ^ Reserved method must return a value
(Buffer required for _CRS)
