This change ensures that the hw-fence driver is disabled by default and
can be enabled or disabled based on a kernel command line argument. If
the hw-fence driver is disabled, msm_hw_fence_probe returns an error.

This change adds support to validate the hw_fence driver
by adding IOCTLs that expose the hw_fence interfaces so that
validation clients can register/unregister, create/destroy
and wait/signal fences. IOCTL's will be available for debug
purpose only when the debugfs config is set.

hw_fence driver is not required for taro variants.
Since the Display SI 3.0 is shared with taro dev SI variant,
avoid compiling hw_fence as dlkm for taro target.

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.

Sync fence driver setup only compiles if the CONFIG flag for
sync driver is set, however, this requires config files of the
parent folder to be included, which currently is not happening.
Resolve this problem by including the parent mm-drivers
config files.

This change adds an api to check if a given speculative
fence is bound. If fence is not bound, it will wait for the
speculative fence ioctl to bind the fence, or else timeout.

This change acquires fence_lock to serialize the enable_sw
signalling operation on dma_fence_array. It bails out
safely if the bind operation is called twice on the spec
fence. The error level for bind failure with invalid user fd
is changed to warning as this case can be treated non fatal.
