pau: mmio invalidates
The remaining translation mode: OpenCAPI 5.0 with TLBI/SLBI Snooping, is
not used due to performance problems caused by the mismatch between the
ERAT and Bloom Filter sizes.
When the Address Translation Mode requires TLB and SLB Invalidate
operations to be initiated using MMIO registers, a set of registers like
the following is used:
• XTS MMIO ATSD0 LPARID register
• XTS MMIO ATSD0 AVA register
• XTS MMIO ATSD0 launch register, write access initiates a shoot down
• XTS MMIO ATSD0 status register
