[Qemu-ppc] [RFC PATCH 0/3] pseries: Fix and extend PAPR RTC implementati

At the moment, the PAPR RTC implementation (actually a paravirt
firmware interface, rather than a normal device) works directly off
host time, and so doesn't respect the options such as clock=vm which
can be specified in the -rtc command line option.

This series is a first cut at addressing this.  Caveats:

  * I haven't yet investigated how clock=vm will interact with
    migration.  I suspect badly.

  * We also use a time stamp when delivering RTAS events in
    spapr_events.c.  For now I haven't changed the code here which
    uses host time (via qemu_get_timedate()).  It's not entirely clear
    which clock these timestamps should be linked to.
