Servo V2 has two FT4232H parts. The first one (denoted 'legacy') is
dedicated to supporting orginal Servo V1 functionality. The second,
residing at USB ID 0x18d1:5003 provides two other SPI interfaces on
port A and B respectively.
Additional changes by Alexandru Gagniuc, Hatim Kanchwala and Urja Rannikko:
- The clock divisor is set to '6', as this creates a 10MHz SPI clock,
which is the same SPI clock that the chromiumos branch produced.
- Add udev rule for Google servo boards to util/flashrom.rules.
- Add Google servo entry to manpage.
Corresponding to flashrom svn r1925.
