95% of the calls inside SOF to TX an IPC don't care about a reply. Yet
the previous commit cleaned up a bunch of replies that were being
populated and then thrown away. This adds some functions so users who do
not need replies don't feel obligated to provide the space to the API.

Provide a way for the client drivers to query the maximum payload size of
an IPC message.
Currently clients do not have access to this information and they can only
use the SOF_IPC_MSG_MAX_SIZE defined value.

A client in the SOF (Sound Open Firmware) context is a driver that needs
to communicate with the DSP via IPC messages. The SOF core is responsible
for serializing the IPC messages to the DSP from the different clients.
One example of an SOF client would be an IPC test client that floods the
DSP with test IPC messages to validate if the serialization works as
expected.
Multi-client support will also add the ability to split the existing audio
cards into multiple ones, so as to e.g. to deal with HDMI with a dedicated
client instead of adding HDMI to all cards.
This patch introduces descriptors for SOF client driver and SOF client
device along with APIs for registering and unregistering a SOF client
driver, sending IPCs from a client device and accessing the SOF core
debugfs root entry.
Along with this, add a couple of new members to struct snd_sof_dev that
will be used for maintaining the list of clients.
