[PATCH 5/5] regulator: fan53555: Use of_property_read_u32_default() for DT parsing

["Peng Fan (OSS)" <peng.fan@oss.nxp.com>]

From: Peng Fan <peng.fan@nxp.com>

Simplify DT parsing of the optional "fcs,suspend-voltage-selector"
property by using of_property_read_u32_default().

If the property is not specified, default to FAN53555_VSEL_ID_0,
which matches the existing behaviour where the field was zeroed
by devm_kzalloc().
