Outputs x8..x0 of the qt2160 can have leds attached to it.
This patch handles those outputs using the generic LED
framework.

The PWM controls available in the chip are used to achieve
different levels of brightness.

In imx_keypad_inhibit(), all 8 columns were set to open-drain, in
contrast to the rest of the driver, where only the enabled columns
are modified/used.

Contrary to the normal expectation, this also affects column I/Os not
even mapped via IOMUX to the KPP hardware module but used as a GPIO.
Therefore only init enabled columns to open-drain and leave all others
with their default reset value of 0, i.e. totem-pole.
