leds: pca955x: Allow zero LEDs to be specified
It's valid to use the PCA955x devices just for GPIOs and not for LEDs.
In this case, as PCA955X_TYPE_GPIO is now equivalent to
PCA955X_TYPE_NONE, remove the test for whether we have any child nodes
specified in the devicetree.
A consequence of this is it's now possible to bind the driver to a
PCA955x device when dynamically instantiated through the I2C subsystem's
`new_device` interface.
