Input: atmel_mxt_ts - use mxt_acquire_irq in mxt_soft_reset
If using IRQF_TRIGGER_FALLING, then there is a race here: if the reset
completes before we enable the IRQ, then CHG is already low and touch
will be broken.
This has been seen on Chromebook Pixel 2.
A workaround is to reconfig T18 COMMSCONFIG to enable the RETRIGEN bit
using mxt-app:
mxt-app -W -T18 44
mxt-app --backup
