regmap: irq: enable wake support by default
regmap-irq framework is used vastly by mfd drivers and some of devices like TPS65910, TPS80036 do not support the wake base register to enable wake. Currently wake in regmap-irq only supported if client driver passes the wake base register. As the regmap-irq is mostly used by mfd devices and it is require to have wake support from these devices in most of use cases, enabling wake support by default in regmap-irq.
