Subject: [PATCH] irqchip/irq-imx-gpcv2: Remove unused function

From: Fabio Estevam <fabio.estevam@....com>

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?
