ASoC: meson: meson-card-utils: use of_property_present() for DT parsing

Commit c141ecc ("of: Warn when of_property_read_bool() is used on
non-boolean properties") added a warning when trying to parse a property
with a value (boolean properties are defined as: absent = false, present
without any value = true). This causes a warning from meson-card-utils.

meson-card-utils needs to know about the existence of the
"audio-routing" and/or "audio-widgets" properties in order to properly
parse them. Switch to of_property_present() in order to silence the
following warning messages during boot:
  OF: /sound: Read of boolean property 'audio-routing' with a value.
  OF: /sound: Read of boolean property 'audio-widgets' with a value.
