On R-Car:

    OF: /sound: Read of boolean property 'simple-audio-card,bitclock-master' with a value.
    OF: /sound: Read of boolean property 'simple-audio-card,frame-master' with a value.

or:

    OF: /soc/sound@ec500000/ports/port@0/endpoint: Read of boolean property 'bitclock-master' with a value.
    OF: /soc/sound@ec500000/ports/port@0/endpoint: Read of boolean property 'frame-master' 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.

Replace testing for presence before calling of_property_read_u32() by
testing for an -EINVAL return value from the latter, to simplify the
code.
