CHROMIUM: Input: atmel_mxt_ts - use client name for irq

The atmel_mxt_ts driver can support multiple devices simultaneously.
Use the i2c_client name instead of the driver name when requesting an
interrupt to make the different interrupts distinguishable in
/proc/interrupts and top.

BUG=chrome-os-partner:8547
TEST=cat /proc/interrupts
  => Should see i2c client name listed for each atmel_mxt_ts device
