    irqchip/irq-imx-gpcv2: Remove unused function
    
    imx_gpcv2_get_wakeup_source() is not used anywhere, so remove it.
    
    This fixes the following sparse warning:
    
    drivers/irqchip/irq-imx-gpcv2.c:34:5: warning: symbol 'imx_gpcv2_get_wakeup_source' was not declared. Should it be static?
    
    Fixes: e324c4dc4a59 ("irqchip/imx-gpcv2: IMX GPCv2 driver for wakeup sources")
