[PATCH/bios_extract] Add support for Phoenix FFV layouts

[Joshua Roys]

Hello,

This patch was developed through some guesswork and by examining the 
debug output of "official" tools.  Expected output looks like:

Using file "../882.bin" (1024kB)
Found Phoenix BIOS "PhoenixBIOS 4.0 Release 6.1     "
Version "DEVEL972", created on 07/07/08 at 15:37:46.
BCPSYS module offset is NULL.
FFV modules: 5

Note that many newer Phoenix BIOSes have a trailer containing flash 
enable information, etc. which must be stripped off for this code to work.

ESCD seems to be "Extended System Configuration Data" (dumped to 
ESCD.bin) and all holes are dumped to hole_%02x.bin.
