host1x_emu: DT Property based syncpoint memory
...
This change uses DT property to select syncpoint memory.
If property "syncpoints-mem" is defined hypervisor syncpoint
memory mechanism is used. Otherwise memory is allocated from
guest kernel.
Previously this was based on code level MACRO. Changing it to
DT simplify selection of syncpoint memory.

The driver remove function is a function pointer and therefore, it does
not make sense to define the function as an 'inline'. Update the
