Some circumstances call for virtual pages, to expose multiple values packed into an extended PMBus register in a manner non-compliant with the PMBus standard. An example of this is the Maxim MAX31785 controller, which extends the READ_FAN_SPEED_1 PMBus register from two to four bytes to support tach readings for both rotors of a dual rotor fan. This extended register contains two word-sized values, one reporting the rate of the fastest rotor, the other the rate of the slowest. The concept of virtual pages aids this situation by mapping the page number onto the value to be selected from the vectored result. We should not try to set virtual pages on the device as such a page explicitly doesn't exist; add a flag so we can avoid doing so.
