Input: tsc2007 - use disable_irq_nosync() in irq handler
disable_irq() waits for all running handlers to complete before
returning. As such, if it's used to disable an interrupt from
that interrupt's handler it will deadlock. This replaces the
dangerous instances with the _nosync() variant which doesn't have
this problem.
