Add ich_descriptor_tool to decode all flash descriptors stored in a flash dump file
This patch adds an external utility that shares most of the existing descriptor decoding source code. Additionally to what is available via FDOC/FDOD this allows to access: - the softstraps which are used to configure the chipset by flash content without the need for BIOS routines. on ICH8 it is possible to read those with FDOC/FDOC too, but this was removed in later chipsets. - the ME VSCC (Vendor Specific Component Capabilities) table. simply put, this is an SPI chip database used to figure out the flash's capabilities. - the MAC address stored in the GbE image. Intel thinks this information should be confidential for ICH9 and up, but references some tidbits in their public documentation. This patch includes the human-readable information for ICH8, Ibex Peak (5 series) and Cougar Point (6 series); the latter two were obtained from leaked "SPI Flash Programming Guides" found by google. Data regarding ICH9 and 10 is unknown to us yet. It can probably found in: "Intel® ICH7, ICH8, ICH9 and ICH10 — SPI Family Flash Programming Guide" Information regarding the upcoming Panther Point chipset is also not included.
