util/amdfwtool: Split type field for PSP entries
Separate the type field for the PSP directory table to better match the AMD Platform Security Processor BIOS Architecture Guide (order #55758, NDA only). Instead of a 32-bit type, change to an 8-bit value and an 8-bit subprogram field to allow for a more generic application across family/model products. This patch also eliminates the "fanless" types, previously added for stoneyridge, and converts the --smufnfirmware and --smufnfirmware2 arguments to use a subprogram value of 1. Subsequent patches will change the stoneyridge makefile to use the new option, and eliminate the fanless arguments. TEST=Boot google/grunt, confirm no difference in amdfw.rom file.
