PCI: iproc: Use of_property_read_bool() for boolean properties

Replace low-level property access functions like of_get_property() and
of_find_property() with their typed equivalents (i.e., of_property_read_<type>
functions), as it's preferred to use typed property access functions for
reading properties.
