IB/hfi1: Guard against concurrent I2C access across all chains The discrete ASIC board design makes the two I2C chains not independent of each other. That is, only one chain can safely be accessed at a time. For discrete ASIC devices, adjust the resource locking so that access to one I2C chain will lock both of the chains.
