Subject: [PATCH 2/4] net: mctp i3c: switch to use i3c_xfer from
 i3c_priv_xfer

Switch to use i3c_xfer instead of i3c_priv_xfer because framework will
update to support HDR mode. i3c_priv_xfer is now an alias of i3c_xfer.

Replace i3c_device_do_priv_xfers() with i3c_device_do_xfers(..., I3C_SDR)
to align with the new API.

Prepare for removal of i3c_priv_xfer and i3c_device_do_priv_xfers().
