ASoC: fsl-asoc-card: Use of_property_present() for non-boolean properties

The use of of_property_read_bool() for non-boolean properties is
deprecated in favor of of_property_present() when testing for property
presence.
Otherwise there'll be kernel warning:
[   29.018081] OF: /sound-wm8962: Read of boolean property 'hp-det-gpios' with a value.
