[PATCH v3 3/7] of: Make of_property_present() applicable to all kinds of property

[Zijun Hu <zijun_hu@xxxxxxxxxx>]

From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx>

API of_property_present() invokes of_property_read_bool() to check if
a property is present or not, and that has 2 shortcomings shown below:

- That narrows down property scope applicable to of_property_present()
  from all kinds of property to only bool type.

- That is less logical since it says a property's presence is decided by
  its bool property value.

Fix by making of_property_read_bool() invoke of_property_present().
