Initial composite kscan driver.

Browse source 
* For now, to be used for FrankenKyria, where both
  matrix halves will be attached to the same MCU, but
  should be a stepping stone to proper split support
  once we have a kscan driver over a split transport.
* Implement multiple instances for mock kscan driver.
