use common cpu_model prasing in vl.c and set default cpu_model
using generic MachineClass::default_cpu_type.
Beside of switching to generic infrastructure it solves several
issues.
* ppc_cpu_class_by_name() is used to deal with lower/upper case
and alias translations into actual cpu type, which fixes
'-M powernv -cpu power8' and '-M powernv -cpu power9_v1.0'
usecases which error out with:
'invalid CPU model 'FOO' for powernv machine'
* allows to switch to lower-case typenames in pnv chip/core name
(by convention typnames should be lower-case)
* replace aliased names /power8, power9, .../ with exact cpu model
names (i.e. typenames should be stable but aliases might decide to
point to other cpu model withi family or changed by kvm). It will
also help to simplify pnv_chip/core code and get rid of dependency

Currently most outbound I/O on the websock channel gets copied into the
rawoutput buffer, and then immediately copied again into the encoutput
buffer, with a header prepended. Now that qio_channel_websock_encode
accepts a struct iovec, we can trivially remove this bounce buffering
and write directly to encoutput.
In doing so, we also now correctly validate the encoutput size against
the QIO_CHANNEL_WEBSOCK_MAX_BUFFER limit.

We must ensure we don't get flooded with ping replies if the outbound
channel is slow. Currently we do this by keeping the ping reply in a
separate temporary buffer and only writing it if the encoutput buffer
is completely empty. This is overly pessimistic, as it is reasonable
to add a ping reply to the encoutput buffer even if it has previous
data in it, as long as that previous data doesn't include a ping
reply.
To track this better, put the ping reply directly into the encoutput
buffer, and then record the size of encoutput at this time in
pong_remain. As we write encoutput to the underlying channel, we
can decrement the pong_remain counter. Once it hits zero, we can
accept further ping replies for transmission.

Reintroduce the write callback that was removed when write support was
removed in commit 023e314856.
Contrary to the previous callback implementation, the write_cb
callback is called whenever a write happened, so handlers must be
ready to handle partial write as necessary.

BlockDriverState has a bdrv_co_drain() callback but no equivalent for
the end of the drain. The throttle driver (block/throttle.c) needs a way
to mark the end of the drain in order to toggle io_limits_disabled
correctly, thus bdrv_co_drain_end is needed.

TPM configuration options are backend implementation details and shall not be
part of base TPMBackend object, and these shall not be accessed directly outside
of the class, hence added a new interface method, get_tpm_options() to
TPMDriverOps., which shall be implemented by the derived classes to return
configured tpm options.
A new tpm backend api - tpm_backend_query_tpm() which uses _get_tpm_options() to
prepare TpmInfo.

This allows backend implementations left optional interface methods.
For mandatory methods assertion checks added.
Took the opportunity to remove unused methods:
- tpm_backend_get_desc()
- TPMDriverOps->handle_startup_error

Initialize and free TPMBackend data members in it's own instance_init() and
instance_finalize methods.
Took the opportunity to remove unneeded destroy() method from TpmDriverOps
interface as TPMBackend is a Qemu Object, we can use object_unref() inplace of
tpm_backend_destroy() to free the backend object, hence removed destroy() from
TPMDriverOps interface.
