leds: leds-st1202: Initialize hardware before DT node child operations

Arguably, there are more chances of errors occurring during the
initialization of the hardware, so this should complete successfully
before the devicetree node's children are initialized.

st1202_dt_init() fills the led_classdev struct.

st1202_setup() initializes the hardware. Specifically, resets the chip,
enables its phase-shift delay feature, enables the device and disables all
the LEDs channels. All that writing to registers, with no input from
st1202_dt_init().

Real-world testing corroborates that calling st1202_setup() before
st1202_dt_init() doesn't cause any issue during initialization.

Switch the order of st1202_dt_init() and st1202_setup() to ensure the
hardware is correctly initialized before the led_classdev struct is
filled.
