Allow configuring the device as wakeup source through device properties, as
not all platforms want to wake up on touch screen activity.
The I2C core automatically reads the "wakeup-source" DT property to
configure a device's wakeup capability, and board supports files can set
I2C_CLIENT_WAKE in the flags.
