pmdomain: ti: Use of_property_present() for non-boolean properties

On BeagleBone Black:

    OF: /ocp: Read of boolean property 'clocks' with a value.
    OF: /ocp/interconnect@44c00000: Read of boolean property 'clocks' with a value.
    OF: /ocp/interconnect@48000000: Read of boolean property 'clocks' with a value.
    OF: /ocp/interconnect@4a000000: Read of boolean property 'clocks' with a value.

The use of of_property_read_bool() for non-boolean properties is
deprecated in favor of of_property_present() when testing for property
presence.
