Add Qualcomm Technologies, Inc. battery charger driver which
interfaces with the charger firmware running on the remote
subsystem (e.g. DSP) by communicating over PMIC Glink channel and
provides information about the battery, USB and wireless charging
by exposing them as power supply devices.

Execute the client's callback in a separate thread to avoid the
following deadlock situation:
- altmode_callback() calls the client's callback when a valid amclient
is found and program execution waits for it to finish.
- The client's callback calls altmode_send_data() to send the PAN_ACK.
- altmode_send_data() eventually calls altmode_write(), which is waiting
for the response_received to be "completed" in altmode_callback().
- For response_received to be "completed", altmode_callback() must
finish executing in order to process the USBC_CMD_WRITE_REQ message
received from the remote subsystem.
- altmode_callback() cannot finish executing until altmode_send_data()
returns.
- altmode_send_data() times out and passes on the error to the client.
Also perform the following:
- Add a check to ensure that the payload received from the remote
subsystem is at least 9 bytes long.
- Prevent out of bounds access for USBC_CMD_WRITE_REQ message (which is
of a different format than struct usbc_notify_ind_msg) by moving the
port_index reading to only the USBC_NOTIFY_IND message in
altmode_callback().

The remote subsystem acknowledges all Altmode PMIC GLINK messages sent
to it. Print an error message anytime it fails to do this.
In the case when no client is found for a received message, do the
sending of the ack in a separate worker thread instead of a plain
function call to altmode_send_ack(). This is to avoid a deadlock and
consequent timing out in altmode_write(), which will happen in the
following scenario:
- A message is received for a nonexistent client.
- altmode_send_ack() is called from within altmode_callback().
- The PAN ACK is sent to the remote subsystem via pmic_glink_write() in
altmode_write() and the remote subsystem replies with an ACK (opcode
USBC_CMD_WRITE_REQ).
- Subsequently, in altmode_write() we wait for completion timeout, which
will happen only if this new ACK message is processed by PMIC GLINK.
- PMIC GLINK is waiting for altmode_callback() to return so that it can
process the new message.
- We are still waiting in altmode_callback() for altmode_send_ack() to
complete.
- We time out in altmode_write() waiting for the completion to occur.
This problem is solved by firing off a worker thread to send the PAN ACK
so that altmode_callback() can exit quickly and allow the incoming new
ACK to hit the complete() in the USBC_CMD_WRITE_REQ case in
altmode_callback().
Also add a couple of minor fixes to some debug messages while we're at
it.

Remove the device tree property "qcom,altmode-name" and the logic it
feeds as it was meant to help in the cases when there are multiple
altmode devices. Since there is going to be only one altmode device as
per design, this is no longer needed.

Client API changes:
- Update client APIs to align them more closely with upstream
conventions.
- In particular, change the link between altmode device and client from
the altmode device's name string to a phandle to the altmode device
followed by the port index of the client.
- Instead of using solely the client's SVID as the key for idr_alloc,
include port_index as well because the unique identifier of a client
is the (SVID, port_index) tuple.
Updates to client notifying mechanism:
- Get rid of the standard notifier APIs in favour of a simpler callback
function-based mechanism to notify clients of probe completion.
- In addition, if clients probe after altmode finishes probing, they
will not get notified of probe completion as this is done only once at
the end of altmode_probe(). Fix this so that if a client registers for
probe completion notifications after altmode probes, they get notified
immediately.
While at it, get rid of the global list of altmode devices (amdev_list)
as there will only be a single altmode device in the system as per
design.

The Type-C standard defines various "alternate (alt) modes" which enable
standard Type-C connectors to carry non-USB signals and data.
This driver provides an interface for Type-C alternate mode clients to
receive data such as Pin Assignment Notifications from the Type-C stack
running on a remote subsystem (e.g. DSP) via the PMIC GLINK interface.

The PMIC Glink driver provides the interface for clients to
communicate over GLink for sending and receiving data to charger
firmware that runs on a remote subsystem (e.g. ADSP) which
supports charging and gauging.
This enables clients to read/write battery charging parameters
and get notifications.
