improve MHI host driver handling.

How does it improve the handling?

Main reason is we want to ensure the MHI controller is zero-initialized and
we want to mandate it as it is better to have it under our control in case
we also want to allocate and track peripheral data/memory related to the MHI
controller.
This also fixes a memory leak as the MHI controller was allocated but
never freed.

For ath11k patches please CC ath11k and linux-wireless lists so that
patchwork sees it. So you need to resend this.

Is this a new API? I need to understand if there are any dependencies
between mhi and ath trees, or if I can apply this directly to my ath.git
tree.

This one should be dependent on the patch [1] which exists on mainline and
should already part of your tree if you're on any 5.10 RC.
