zbao 85f362e9b6 amdfwtool: Fill the first 3 romsig entries as 0
I didn't go back through the development guide for this.
But based on test, if the empty entry is filled as 0xFFFFFFFF,
instead of 0, the USB3 port can not be used.

Leave the entries of PSP and PSP2 as 0xFFFFFFFF to be compliant
with the case before the amdfwtool is used.

* 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.
