[PATCH v2] iio: light: tsl2563 change of_property_read to device_property_read

[Vaishnav M A]

replace the of_property_read_u32 for reading the amstaos,cover-comp-gain
property with device_property_read_u32,allows the driver to
get the properties information using the more generic device_property_*
helpers and opens the possibility of passing the properties during
platform instantiation of the device by a suitably populated
struct property_entry.
