Subject: [PATCH] mfd: max8997: Enale irq-wakeup unconditionally

IRQ wakeup support for MAX8997 driver was initially configured by
respective property in pdata. However, after the driver conversion to
device-tree, setting it was left as 'todo'. Nowadays most of other MAX PMIC
MFD drivers initialized from device-tree simply assume unconditionally that
they can be an irq wakeup source, so enable wakeup support also for
MAX8997. This fixes support for wakeup from MAX8997 RTC alarm.
