Introduce mhi_get_free_desc_count() API to return number
of TREs available to queue buffer. MHI clients can use this
API to know before hand if ring is full without calling queue
API.

In case this series get new comments to address, I would suggest
merging that patch in mhi-next separately so that other drivers can
start benefiting this function (I would like to use it in mhi-net).

Greg doesn't like that. He asked me to pick APIs only when there an in-tree
consumer available.
