Fix the maintenance access functions to farend RapidIO devices. 1. Fixed shift of the given offset, to open the maintenance window 2. Mask offset to limit access to the opened maintenance window 3. Added extended destid part to rowtear register, required for 16bit mode This method is matching maintenance transactions generation described by Freescale in the appnote AN2932. With this modification full access to a 16MB maintenance window is possible, this patch is required for IDT cps switches. For easier handling of the access routines, the access was limited to aligned memory regions. This should be no problem because all registers are 32bit wide.
