MLK-14289 ARM: imx: add inline for unused function

Add inline for unused function to avoid build warning.

For example, when i.MX7D is unselected, below warning
will show during compile:

arch/arm/mach-imx/common.h:163:13: warning:
'imx_gpcv2_add_m4_wake_up_irq' defined but not used
[-Wunused-function]
