irqchip/meson: Disable COMPILE_TEST

The driver fails to compile with CONFIG_COMPILE_TEST=y on x86:

irq-meson-gpio.c: In function ‘meson_gpio_irq_parse_dt’:
irq-meson-gpio.c:343:8: error: implicit declaration of function
			       ‘of_property_read_variable_u32_array’
  ret = of_property_read_variable_u32_array(node,

Adding COMPILE_TEST to a driver requires at least compile testing it for
x86....
