jhibbits 0b4a4336f2 powerpc: Blacklist the top 64kB range of the lower 4GB PA space

The PHB4 host bridge used by the POWER9 uses a 64kB range in 32-bit
space at the address 0xffff0000-0xffffffff.  Reserve this range so that
DMA memory cannot be allocated within this range.  This fixes seemingly
random crashes on a POWER9 system.  Ideally this range will have been
reserved by the firmware, but as of now this is not the case.
