[PATCH] dt-bindings: regulator: fcs,fan53555: Remove vsel-gpios property

The vsel-gpios property is currently documented in the binding but
is not used by the driver. The FAN53555 family of regulators supports
two voltage selector registers (VSEL0/VSEL1), and the selection between
them is intended to be controlled by an external hardware pin (VSEL).
However, the driver does not support dynamic toggling of this pin via
a GPIO, it only uses the fcs,suspend-voltage-selector property to
statically assign which register is used for runtime voltage and which
for suspend voltage.
Remove the vsel-gpios property from the binding to prevent incorrect DT
usage and to reflect the actual hardware description supported by the
driver.
