Subject: [PATCH] mfd: twl6030-irq: Revert to use of_match_device()

The core twl chip is probed via i2c and the dev->driver->of_match_table is
NULL, causing the driver to fail to probe.

This partially reverts commit 1e0c866887f4.

Fixes: 1e0c866887f4 ("mfd: Use device_get_match_data() in a bunch of drivers")
