On target-ppc, our table of CPU types and features encodes the features as
found on the hardware, regardless of whether these features are actually
usable under TCG or KVM. We already have cases where the information from
the cpu table must be fixed up to account for limitations in the emulation
method we're using. e.g. TCG does not support the DFP and VSX instructions
and KVM needs different numbering of the CPUs in order to tell it the
correct thread to core mappings.
This patch cleans up these hacks to handle emulation limitations by
consolidating them into a pair of functions specifically for the purpose.

Currently the pseries machine contains not one but two somewhat ugly hacks
to allow printing of early debug messages before the guest has properly
read the device tree.
First, we special case H_PUT_TERM_CHAR so that a vtermno of 0 (usually
invalid) will look for a suitable vty and use that. This supports Linux's
early debug code which will use H_PUT_TERM_CHAR with vtermno==0 before
reading the device tree. Second, we support the RTAS display-character call. This takes no vtermno
so we assume the address of the default first VTY.
This patch makes things more consistent by folding the second hack into the
first. Now, display-character uses the existing vty_lookup() function to
do the same search for a suitable VTY.

PAPR virtual IO (VIO) devices require a unique, but otherwise arbitrary,
"address" used as a token to the hypercalls which manipulate them.
Currently the pseries machine code does an ok job of allocating these
addresses when the legacy -net nic / -serial and so forth options are used
but will fail to allocate them properly when using -device.
Specifically, you can use -device if all addresses are explicitly assigned.
Without explicit assignment, only one VIO device of each type (network,
console, SCSI) will be assigned properly, any further ones will attempt
to take the same address leading to a fatal error.
This patch fixes the situation by adding a proper address allocator to the
VIO "bus" code. This is used both by -device and the legacy options and
default devices. Addresses can still be explicitly assigned with -device
options if desired.
This patch changes the (guest visible) numbering of VIO devices, but since
their addresses are discovered using the device tree and already differ
from the numbering found on existing PowerVM systems, this does not break
compatibility.
