openpic: BRR1 is not a CPU-specific register.

It's in the address range that normally contains a magic redirection
to the CPU-specific region of the curretn CPU, but it isn't actually
a per-CPU register.  On real hardware BRR1 shows up only at 0x40000,
not at 0x60000 or other non-magic per-CPU areas.  Plus, this makes
it possible to read the register on the QEMU command line with "xp".
