Add a new API "mhi_prepare_for_transfer_autoqueue" for using with client
drivers like QRTR to request MHI core to autoqueue buffers for the DL
channel along with starting both UL and DL channels.

So far, the "auto_queue" flag specified by the controller drivers in
channel definition served this purpose but this will be removed at some
point in future.

Changes in v2:

* Rebased on top of 5.16-rc1
* Fixed an issue reported by kernel test bot
* CCed netdev folks and Greg  

Dave, Jakub, this patch should go through the MHI tree. Since it touches the
QRTR driver, can you please give an ACK?
