Implement host1x_syncpt_get_shim_info function for
host1x-emu driver and add it to the dynamic dispatch
mechanism in host1x-fence.

This function provides clients with the physical address
of syncpoint aperture, stride and number of
syncpoints, which is needed by various client drivers
like ISP, VI, PVA, GPU etc
