Currently spapr_cpu_init() is hardcoded to handle any errors as fatal.
That works for now, since it's only called from initial setup where an
error here means we really can't proceed.
However, we'll want to handle this more flexibly for cpu hotplug in future
so generalize this using the error reporting infrastructure. While we're
at it make a small cleanup in a related part of ppc_spapr_init() to use
error_report() instead of an old-style explicit fprintf().

Current ppc_set_compat() returns -1 for errors, and also (unconditionally)
reports an error message. The caller in h_client_architecture_support()
may then report it again using an outdated fprintf().
Clean this up by using the modern error reporting mechanisms. Also add
strerror(errno) to the error message.

h_client_architecture_support() uses rtas_ld() for general purpose memory
access, despite the fact that it's not an RTAS routine at all and rtas_ld
makes things more awkward.
Clean this up by replacing rtas_ld() calls with appropriate ldXX_phys()
calls.

rtas_st_buffer_direct() is a not particularly useful wrapper around
cpu_physical_memory_write(). All the callers are in
rtas_ibm_configure_connector, where it's better handled by local helper.

rtas_st_buffer() appears in spapr.h as though it were a widely used helper,
but in fact it is only used for saving data in a format used by
rtas_ibm_get_system_parameter(). This changes it to a local helper more
specifically for that function.
While we're there fix a couple of small defects in
rtas_ibm_get_system_parameter:
- For the string value SPLPAR_CHARACTERISTICS, it wasn't including the
terminating \0 in the length which it should according to LoPAPR
7.3.16.1
- It now checks that the supplied buffer has at least enough space for
the length of the returned data, and returns an error if it does not.

Currently the aiocb is held within MACIOIDEState, however the IDE core code
assumes that the current actvie DMA aiocb is held in aiocb in a few places,
e.g. ide_bus_reset() and ide_reset().
Switch over to using IDEDMA aiocb to store the aiocb for the current active
DMA request so that bus resets and restarts are handled correctly. As a
consequence we can now use ide_set_inactive() rather than handling its
functionality ourselves.
