dev-arm: Read correct version of ICC_BPR register

Some methods like groupPriorityMask check for the value of binary point
registers. Those registers have a minimum value.  Writing to those
register is taking this into account, but the problem with the minimum
value arises when the value is checked before sw is writing to them.
In this case the minimum value won't be considered if the read is
directly forwarded to the ISA class.
