mfd: Set twl6030 irq_wake infrastructure up
TWL6030 devices have an interrupt line which is connected to application processor like OMAP. These devices support multiple features such as MMC card detect, USB cable detect, RTC interrupt, etc. that must wake up the application processor. With this change, TWL6030 client drivers can make use of irq_wake() if the wakeup is desirable on it's irq events.
