The mfd mc13xxx interrupt handling was migrated to regmap with commit
10f9edaeaa30 ("mfd: mc13xxx: Use regmap irq framework for interrupts").
As a consequence, button_irq() will get called with virtual irq instead
of chip-internal irq now. Add wrappers for the three supported interrupts.

Use devres functionality to simplify resource freeing, dev.parent will
be set by devm_input_allocate_device().

All three mc13xxx types do feature two common power buttons referred as
ONOFD[12] (mc13783) and PWRON[12] (mc13892/mc34708) in the SoC reference
manuals. Add support for PWRON[12] (mc13892/mc34708) but skip support for
button PWRON3 (mc13892) for sake of simplicity.

Convert the txt mc13xxx bindings to DT schema attempting to keep most
information. The nodes codec and touchscreen are not part of the new
schema since it was only briefly mentioned before.
Following the convention, rename led-control to fsl,led-control.

-Sub-nodes:
-- codec: Contain the Audio Codec node.
- - adc-port: Contain PMIC SSI port number used for ADC.
- - dac-port: Contain PMIC SSI port number used for DAC.
-- leds : Contain the led nodes and initial register values in property
- "led-control". Number of register depends of used IC, for MC13783 is 6,
- for MC13892 is 4, for MC34708 is 1. See datasheet for bits definitions of
- these registers.
- - #address-cells: Must be 1.
- - #size-cells: Must be 0.
- Each led node should contain "reg", which used as LED ID (described below).
- Optional properties "label" and "linux,default-trigger" is described in
- Documentation/devicetree/bindings/leds/common.txt.
-- regulators : Contain the regulator nodes. The regulators are bound using
