iio: dac: mcp47feb02: Fix passing uninitialized vref1_uV for no Vref1 case
Ensure that if a device has Vref1 but reading the regulator returns an
error, mcp47feb02_init_ctrl_regs() is not called with an uninitialized
vref1_uV value. Also add a device_property_present() check for the Vref1
supply before reading the regulator.
