[PATCH] bus: ti-sysc: Use of_property_present()

[Rob Herring (Arm)]

Use of_property_present() to test for property presence rather than
of_get_property(). This is part of a larger effort to remove callers
of of_get_property() and similar functions. of_get_property() leaks
the DT property data pointer which is a problem for dynamically
allocated nodes which may be freed.

The code was also incorrectly assigning the return value to a 'struct
property' pointer. It didn't matter as "prop" was never dereferenced.
