[PATCH] fix Intel RNG detection
Previously, since determination whether there was an Intel random number generator was based on a single bit, on systems with a matching bridge device but without a firmware hub, there was a 50% chance that the code would incorrectly decide that the system had an RNG. This patch adds detection of the firmware hub to better qualify the existence of an RNG. There is one issue with the patch: I was unable to determine the LPC equivalent for the PCI bridge 8086:2430 (since the old code didn't care about which of the many devices provided by the ICH/ESB it was chose to use the PCI bridge device, but the FWH settings live in the LPC device, so the device list needed to be changed).
