Input command can fail (with exceptions) if the touchscreen id is not 0

We had a device where the touchscreen was reconfigured during system
init, and as a result was assigned a device id that was not 0.
The following message from InputReader.cpp was logged when this occured:
I/InputReader(  762): Device reconfigured: id=4, name='himax-touchscreen', size 1024x600, orientation 1, mode 1, display id 0

Attempting to use the input command for the touchscreen in this state
will fail due to the hardcoded touchscreen device id.
