This binding is based on the matrix-keymap binding with the following
changes:

keypad,num-rows and keypad,num-columns are required.

Required properties:
- compatible: "ti,tca8418"
- reg: the I2C address
- interrupts: IRQ line number, should trigger on falling edge
- linux,keymap: Keys definitions, see keypad-matrix.
input: Extend matrix-keypad device tree binding Some matrix keypad drivers can support different numbers of rows and columns. Add a generic binding for these. Implementation note: In order to implement this binding in the kernel, we will need to modify matrix_keypad_() to look up the number of rows and cols in the keymap. Perhaps this could be done by passing 0 for these parameters? Many of the parameters can already be set to NULL. Ick.
