Marshall Dawson 67d868d04b util/amdfwtool: Introduce combo-capable option 
There are effectively two unique sets of arguments for the utility,
causing one of two tables to be constructed.  Both tables are
identical, however, and therefore the only practical difference is
the offset in the Embedded Firmware Structure which holds the pointer
to the table.

This patch is part 1 of 2 to reduce the number of command-line options
to amdfwtool.  Create a new option that is used as an indicator for
which Embedded Firmware offset to use.  Part 2 will be added once
makefiles no longer use the duplicated options.

This patch also adds two new options for fanless SMU firmware to be
used instead of the ones that will be removed in part 2.

TEST=Verify no difference in amdfw.rom for google/grunt before
     and after the patch is applied

* Creates the OSI Fletcher checksum. See 8473-1, Appendix C, section C.3.
* The checksum field of the passed PDU does not need to be reset to zero.
*
* The "Fletcher Checksum" was proposed in a paper by John G. Fletcher of
* Lawrence Livermore Labs. The Fletcher Checksum was proposed as an
* alternative to cyclical redundancy checks because it provides error-
* detection properties similar to cyclical redundancy checks but at the
* cost of a simple summation technique. Its characteristics were first
* published in IEEE Transactions on Communications in January 1982. One
* version has been adopted by ISO for use in the class-4 transport layer
* of the network protocol.
*
* This program expects:
* stdin: The input file to compute a checksum for. The input file
* not be longer than 256 bytes.
* stdout: Copied from the input file with the Fletcher's Checksum
* inserted 8 bytes after the beginning of the file.
* stderr: Used to print out error messages.
