[ Upstream commit 3a748d483d80f066ca4b26abe45cdc0c367d13e9 ]
Some boards with Allwinner SoCs connect the PMIC's IRQ pin to the SoC's NMI pin instead of a normal GPIO. Since the power key is connected to the PMIC, and people expect to wake up a suspended system via this key, the NMI IRQ controller must stay alive when the system goes into suspend.
Add the SKIP_WAKE flag to prevent the sunxi NMI controller from going to sleep, so that the power key can wake up those systems.
[ tglx: Fixed up coding style ]
