drivers/sensor: iis2mdc: use gpio_dt_spec oriented macros

Use gpio_pin_configure_dt() and gpio_pin_interrupt_configure_dt()
for drdy_gpio: they result in a more readable code.

Moreover, this commit includes also the fix for PR #35156
(i.e. CID 235979, add check for gpio_pin_configure() return val).
