mfd: iqs62x: Provide device revision to sub-devices
Individual sub-devices may elect to make decisions based on the specific revision of silicon encountered at probe. This data is already read from the device, but is not retained. Pass this data on to the sub-devices by adding the software and hardware numbers (registers 0x01 and 0x02, respectively) to the iqs62x_core struct.
