input: Add support for keyboard matrix decoding from an fdt
Matrix keyboards require a key map to be set up, and must also deal with
key ghosting.
Create a keyboard matrix management implementation which can be leveraged
by various keyboard drivers. This includes code to read the keymap from
the FDT and perform debouncing.
