The pinctrl settings were incorrect for the touchscreen interrupt line, causing
an interrupt storm. This change has been tested with both the atmel_mxt_ts and
RMI4 drivers on the RDU1 units.

The pinctrl settings were incorrect for the touchscreen interrupt line, causing
an interrupt storm. This change has been tested with both the atmel_mxt_ts and
RMI4 drivers on the RDU1 units.
The value 0x4 comes from the value of register IOMUXC_SW_PAD_CTL_PAD_CSI1_D8
from the old vendor kernel.

Tested on an RDU1 with Synaptics touchscreen successfully. No
interrupt store any longer...

You do not have to send new version just for collecting review and test
tags. I will do that when applying.
