Add support for Winbond W39V040FB and W39V040FC
Print lock status for all supported Winbond W39* chips: W39V040A, W39V040B, W39V040C, W39V040FA, W39V040FB, W39V040FC, W39V080A, W39V080FA, W39V080FA (dual mode). Fill in correct probe timing for Winbond W39V040C and W39V080FA. Please note that the W39V040B/W39V040FB pair has identical IDs, identical read/write/erase, but locking differs. Same applies to W39V040C/W39V040FC. This causes double detection on chipsets which support LPC and FWH, making flashing more difficult because the user has to select the correct chip. This is called the evil twin problem. A better evil twin handling (patch available) will resolve that problem. Corresponding to flashrom svn r1245.
