Subject: [PATCH 3/6] Input: da9052_tsi.c: Fix interrupt handling

From: Fabio Estevam <fabio.estevam@...escale.com>

Currently da9062_tsi does not probe and it fails as follows:

da9052 1-0048: Unable to determine device interrupts

Use the new da9052 irq functions and allow the driver to probe and operate 
correctly.

Tested on mx53qsb board using 'evtest' tool.
