input: gpio_kbd_matrix: add column drive mode Add an option to drive inactive columns to inactive state rather than high impedance. This is useful if the matrix has isolation diodes for every key, as it allows the matrix to stabilize faster and the API for changing the pin value is more efficient than the one to change the pin configuration.
