target/ppc: Add SMT support to time facilities
The TB, VTB, PURR, HDEC SPRs are per-LPAR registers, and the TFMR is a
per-core register. Add the necessary SMT synchronisation and value
sharing.
The TFMR can only drive the timebase state machine via thread 0 of the
core, which is almost certainly not right, but it is enough for skiboot
and certain other proprietary firmware.
