Mikko Perttunen af2a177038 gpu: host1x: Retrieve syncpoint shim information ...

Retrieve information for the memory syncpoint shim from the device tree
and add an interface to provide the information to other drivers.

The memory syncpoint shim is a special area on the data backbone,
where each memory page corresponds to a host1x syncpoint. Reading
the page returns the value of the syncpoint, and writing to it
increments the syncpoint by one.
