Some clients require that write_index starts from nonzero value and
index by payload instead of by dwords. Add support for device-tree
configurable properties to control nonzero index start_index and
indexing by payload for client tx queue read and write indices.

Add device-tree configurable padding in bytes before and after queue
header(s). This enables support for 32-byte aligned queue write_idx,
which is a requirement to satisfy hardware constraints by some clients.

Some hw fence driver clients require the ability to call the
'msm_hw_fence_update_txq' API to update the queue payload without
updating the 'write_index' member within the hfi header. These clients
also need to receive the index at which the payload is written within
the queue.
This change adds support for this requirement by adding a device-tree
property to configure this behavior for each client. The 'tx_wm' member
within the hfi header is used to track in software the place where the
payloads are within the queue for clients that skip the update to the
'write_index' member.

Update hw fence driver to support new clients with large number
of possible sub-clients, which can be configured in device-tree.
Add client queues support for ipe, vpu, and ife clients.

This change adds support for the hw-fence driver that initialize, expose
and manage the interfaces for the hw-fences, which are the synchronization
primitives to allow the hardware to hardware signalization of the fences
for the frame buffers shared between gpu and display hw-cores.
