    Revert "google/pyro: remove Wacom touchscreen probed flag"
    
    This reverts commit 1099c665091b64bff3c01234826e8c7640a7b8f6
    
    Reason for revert:
    Pyro has two touchscreen sources: WACOM/ELAN.
    It will not have both touchscreen IC in one system at the same time.
    
    So the "probed" property of WACOM i2c device is mandatory to set for kernel
    to know whether it exists before driver initializes it.
    
    Otherwise in ELAN case, when driver fails to init WACOM i2c device, ACPI _OFF
    will be invoked to set GPIO#152 low to cut off power.
