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.

When validation clients register to wait on already signaled fences,
the hw fence driver must signal the client wait and wake up waiting
validation clients.

This change make sure that the write_idx and read_idx

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 configurable parameters for
each client type, which can be set up through device-tree. This
allows configuring number of queues (e.g. only Tx Queue or both
Rx and Tx Queues), number of entries per client queue, and number
of sub-clients for each client-type.

Add support of the option to pass a 64-bit client_data value to
the hw fence driver when a client registers as a waiting client
for a hardware fence. Then during fence signaling, this client_data
is returned to the client via the RxQ.
If no client_data is passed to the driver for the hw fence, then a
default value of zero is registered as the client_data.

Not all clients need ipc interrupt for an already signaled fence. Set the
per client property based on whether a client needs the interrupt or not.
Also, set update_rxq property for GPU client to false, as GPU doesn't need
already signaled fences to be sent to GPU Rx Queue.
