Clients store their private data in user within event structure
and not in notify structure. Thus update the callback to point
to the correct user info.

Use the locally calculated value of memory attribute entries when
populating the memory attribute descriptor, instead of always
dereferencing the client provided memory attribute descriptor,
as clients may not always provide one.

Add subsystem restart (SSR) support to altmode glink driver so
that when subsystem goes down and comes up again, it can send
PAN_EN to charger firmware to receive notifications about altmode
interface.

Add subsystem restart (SSR) support to battery charger driver so
that it can stop read/write properties when subsystem goes down.
Also, send message to enable notification again once subsystem
comes up.

Add subsystem restart (SSR) support to UCSI Glink driver so that
it can unregister from UCSI framework when subsystem goes down
and register with UCSI framework when it comes up again. When
subsystem goes down, it is not possible for UCSI stack to send
or receive data to and from PPM (i.e. remote subsystem) over
PMIC Glink. Hence, return immediately in ucsi_qti_{read,write}()
to avoid error logs and handle cleanup easily.

Add support for PMIC Glink clients to receive notification when
the subsystem goes down and comes up again. PMIC Glink client
can pass a function pointer state_cb via which they would like
to receive when PMIC Glink state transitions so that they can
unregister from the framework (e.g. UCSI) and clean up their
state as needed.
PMIC Glink device supports SSR for the subsystem specified under
"qcom,subsys-name" property.

In preparation for subsystem restart (SSR) and protection domain
restart (PDR) where subsystem state transitions would be sent to
PMIC Glink clients via another callback function, change the client
callback function pointer name to msg_cb. This would convey that
this callback is for delivering the messages to a client upon its
registration.

Currently, the clients of the hh_msgq driver would allocate buffers,
fill with data and call hh_msgq_send(). Upon success, hh_msgq_send()
would be freeing the buffer, while in the case of failure, the clients
are responsible for it. However, this approach of buffer management is
not symmetric and could be confusing for the clients. Hence, let the
clients take full ownership of the buffers- allocating and freeing.
Also make changes to the affected client drivers.

It's a highly likely situation that the clients call hh_msgq_recv()
from a thread in a polling fashion, and these threads are spawned
during client driver's initialization. Hence, it's possible that
the cap-ids for the message queues will not be ready so early and
the clients would end up continuously spinning on hh_msgq_recv(),
receiving the error -EAGAIN. To avoid this situation, put the
client process onto a wait-queue until the cap-ids are ready.
Although a little unlikely, to satisfy the symmetry, add the same
provision for the callers of hh_msgq_send() as well.

hh_msgq_register() can now return -EPROBE_DEFER as an error code.
Since this is not a fatal error, and will end up in having the
probe function called again at a later point in time, do not
print an error when -EPROBE_DEFER is returned.
