[PATCH v2] ASoC: ak4642: Drop "clocks" property presence check

["Rob Herring (Arm)" <robh@kernel.org>]

of_property_read_bool() should only be used on boolean properties and
not used as a presence check. The of_clk_get_parent_name() function
returns NULL if the "clocks" property is not present, so there is no
need to check for presence first.

Signed-off-by: Rob Herring (Arm) <robh@kernel.org>

v2:
 - Just drop the presence check instead of using of_property_present()
 - Split to separate patch
