Add selfcheck_board_enables().

Check for NULL termination of the array, that each board has the two
main PCI ID sets defined, that coreboot vendor and model fields are either
both set or unset, and that at least either an enable function or a max
decode size is available.

 /* Parse the <vendor>:<board> string specified by the user as part of -p internal:mainboard=<vendor>:<board>.
  * Parameters vendor and model will be overwritten. Returns 0 on success.
  * Note: strtok modifies the original string, so we work on a copy and allocate memory for the results.
