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.
