Keyboard: Allow keyboard size to be set at run time
Currently, the keyboard size (i.e. number of columns) is static.
This patch allows it to be configured at run time. It's required to
support a keyboard with/without keypad in a single image.
KEYBOARD_COLS_MAX has the build time col size. It's used to allocate
exact spaces for arrays. Actual keyboard scanning is done using
keyboard_cols, which holds a runtime col size.
