[PATCH] ASoC: soc-core: Use of_property_present() for non-boolean properties

[Fabio Estevam <festevam@gmail.com>]

From: Fabio Estevam <festevam@denx.de>

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

Switch to of_property_present() to fix the following warnings observed
when booting the imx8mp-evk board:

[   11.436855] OF: /sound-bt-sco/simple-audio-card,cpu: Read of boolean property 'dai-tdm-slot-num' with a value.
[   11.436885] OF: /sound-bt-sco/simple-audio-card,cpu: Read of boolean property 'dai-tdm-slot-width' with a value.
[   11.436941] OF: /sound-bt-sco: Read of boolean property 'simple-audio-card,bitclock-master' with a value.
[   11.436960] OF: /sound-bt-sco: Read of boolean property 'simple-audio-card,frame-master' with a value.

Based on Rob Herring's patch for mmc.
