MFC r279723, r279724:

  Define new linker set, UART_FDT_CLASS_AND_DEVICE, for registering full
  (class and device) FDT UART. Define second one, UART_FDT_CLASS, for UART
  class only.

  Move the uart_class definitions and fdt compat data into the individual
  uart implementations, and export them using the new linker-set mechanism.
