     retries transaction, and then resets the touchpad power.

4cb524de67 touchpad_elan: Rename task/interrupts functions
Change the names to generic touchpad_* functions, instead of
vendor-specific names. Makes it a little easier to add drivers
for other touchpads.

Also fix console_channel.inc to add the channel whenever any
touchpad is used.
