media: cros-ec-cec: Get number of CEC ports from EC
Add a new CEC port count host command and use it to query the number of
CEC ports from the EC. If the host command is not supported then it must
be old EC firmware which only supports one port, so fall back to
assuming one port.
This patch completes support for multiple ports in cros-ec-cec.

media: cros-ec-cec: Support receiving messages from multiple ports
Currently, received messages are sent from the EC in the cec_message
MKBP event. Since the size of ec_response_get_next_data_v1 is 16 bytes,
which is also the maximum size of a CEC message, there is no space to
add a port parameter. Increasing the size of
ec_response_get_next_data_v1 is an option, but this would increase
EC-kernel traffic for all MKBP event types.
Instead, use an event to notify that data is ready, and add a new read
command to read the data.
For backwards compatibility with old EC firmware, continue to handle
cec_message events as well.

Add a v1 of the CEC write command which contains a port parameter. Check
which versions of the write command the EC supports and use the highest
supported version. If it only supports v0, check that there is only one
port. With v0, the EC will assume all write commands are for port 0.

media: cros-ec-cec: Support multiple ports in set/get host commands
Reuse the top four bits of the cmd field to specify the port number.
The reason for doing this as opposed to adding a separate uint8_t field
is it avoids the need to add new versions of these commands. The change
is backwards compatible since these bits were previously always zero, so
the default behaviour is to always operate on port 0.

To support multiple CEC ports, change cros_ec_cec to contain an array of

For now, only create a single port and use that port everywhere, so

media: cros-ec-cec: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
