'chinfo.name' is used as a NUL-terminated string, but using strncpy() with
the length equal to the buffer size may result in lack of the termination:

drivers//soc/qcom/wcnss_ctrl.c: In function 'qcom_wcnss_open_channel':
drivers//soc/qcom/wcnss_ctrl.c:284:2: warning: 'strncpy' specified bound 32 equals destination size [-Wstringop-truncation]
  strncpy(chinfo.name, name, sizeof(chinfo.name));
  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This changes it to use the safer strscpy() instead.

hdr.len includes both the size of the header and the fragment, so using
this when stepping through the firmware causes us to skip 16 bytes every
chunk of 3072 bytes; causing only the first fragment to actually be
valid data.

Instead use fragment size steps through the firmware blob.

By moving these client drivers to use RPMSG instead of the direct SMD
API we can reuse them ontop of the newly added GLINK wire-protocol
support found in the 820 and 835 Qualcomm platforms.

As the new (RPMSG-based) and old SMD implementations are mutually
exclusive we have to change all client drivers in one commit, to make
sure we have a working system before and after this transition.

We need the signal from wcnss_ctrl indicating that the firmware is up
and running before we can communicate with the other components of the
chip. So make these other components children of the wcnss_ctrl device,
so they can be probed in order.

The process seems to take between 1/2-5 seconds, so this is done in a
worker, instead of holding up the probe.

By passing the smd channel reference to the callback, rather than the
smd device, we can open additional smd channels from sub-devices of smd
devices.

Also updates the two smd clients today found in mainline.
